Answers

To obtain the numerical solution of the given ordinary differential equation using the Euler method, with a step size of h = 0.5 and the initial condition y(0) = -2, we perform three steps. The solution will be obtained with four digits after the decimal point.

The Euler method is a numerical method used to approximate the solution of a first-order ordinary differential equation. It uses discrete steps to approximate the derivative of the function at each point and updates the function value accordingly. Given the differential equation y' = 3t - 10y², we can use the Euler method to approximate the solution. Using the initial condition y(0) = -2, we can start with t = 0 and y = -2. To perform three steps with a step size of h = 0.5, we increment the value of t by h in each step and update the value of y using the Euler's formula:

y[i+1] = y[i] + h * f(t[i], y[i])

where f(t, y) represents the derivative of y with respect to t.

By performing these three steps and calculating the values of t and y at each step with four digits after the decimal point, we can obtain the numerical solution of the given differential equation using the Euler method.

Answers

Given data: Minimum pressure on an object = 80 kPa (absolute)Velocity of an object = (x+5) mm/sDepth of an object = 1mTemperature = 10°CAtmospheric pressure = 100 kPa (absolute)

We know that the minimum pressure to initiate cavitation is given as:pc = pa - (pv)²/(2ρ)Where, pa = Atmospheric pressurepv = Vapour pressure of liquidρ = Density of liquidNow, the vapour pressure of water at 10°C is 1.223 kPa (absolute) and density of water at this temperature is 999.7 kg/m³.Substituting the values in the above equation, we get:80 = 100 - (pv)²/(2×999.7) => (pv)² = 39.706

A jet of water 0.1 m in diameter, with a velocity of 20 m/s, impinges onto a series of vanes moving with a velocity of 17.5 m/s. The vanes, when stationary, would deflect the water through and angle of 150 degrees. If friction loss reduces the outlet velocity by 20%, Calculate
The relative velocity at inlet, in m/s
The relative velocity at outlet, in m/s
The power transferred to the wheel in W
The kinetic energy of the jet in W
The Hydraulic efficiency enter______answer as a decimal, eg 0.7 NOT 70%

Answers

Relative velocity at the inlet: 2.5 m/s

Relative velocity at the outlet: -1.5 m/s

Power transferred to the wheel: 10,990 W

Kinetic energy of  the jet: 78,500 W

Hydraulic efficiency: 0.14

To solve this problem, we can use the principles of fluid mechanics and conservation of energy. Let's go step by step to find the required values.

1. Relative velocity at the inlet:

The relative velocity at the inlet can be calculated by subtracting the velocity of the vanes from the velocity of the water jet. Therefore:

Relative velocity at the inlet = Water jet velocity - Vane velocityRelative velocity at the inlet = 20 m/s - 17.5 m/sRelative velocity at the inlet = 2.5 m/s

2. Relative velocity at the outlet:

The outlet velocity is reduced by 20% due to friction losses. Therefore:

Outlet velocity = Water jet velocity - (Friction loss * Water jet velocity)Outlet velocity = 20 m/s - (0.20 * 20 m/s)Outlet velocity = 20 m/s - 4 m/sOutlet velocity = 16 m/s

To find the relative velocity at the outlet, we subtract the vane velocity from the outlet velocity:

Relative velocity at the outlet = Outlet velocity - Vane velocityRelative velocity at the outlet = 16 m/s - 17.5 m/sRelative velocity at the outlet = -1.5 m/s

(Note: The negative sign indicates that the water is leaving the vanes in the opposite direction.)

3. Power transferred to the wheel:

The power transferred to the wheel can be calculated using the following formula:

Power = Force * VelocityForce = Mass flow rate * Change in velocity

To calculate the mass flow rate, we need to find the area of the water jet:

Area of the water jet = π * (diameter/2)²Area of the water jet = 3.14 * (0.1 m/2)²Area of the water jet = 0.00785 m²

Mass flow rate = Density * Volume flow rate

Volume flow rate = Area of the water jet * Water jet velocity

Density of water = 1000 kg/m³ (assumed)

Mass flow rate = 1000 kg/m³ * 0.00785 m^2 * 20 m/s

Mass flow rate = 157 kg/s

Change in velocity = Relative velocity at the inlet - Relative velocity at the outlet

Change in velocity = 2.5 m/s - (-1.5 m/s)

Change in velocity = 4 m/s

Force = 157 kg/s * 4 m/s

Force = 628 N

Power transferred to the wheel = Force * Vane velocity

Power transferred to the wheel = 628 N * 17.5 m/s

Power transferred to the wheel = 10,990 W (or 10.99 kW)

4. Kinetic energy of the jet:

Kinetic energy of the jet can be calculated using the formula:

Kinetic energy = 0.5 * Mass flow rate * Velocity²

Kinetic energy of the jet = 0.5 * 157 kg/s * (20 m/s)²

Kinetic energy of the jet = 78,500 W (or 78.5 kW)

5. Hydraulic efficiency:

Hydraulic efficiency is the ratio of power transferred to the wheel to the kinetic energy of the jet.

Hydraulic efficiency = Power transferred to the wheel / Kinetic energy of the jet

Hydraulic efficiency = 10,990 W / 78,500 W

Hydraulic efficiency ≈ 0.14

Therefore, the answers are:

Relative velocity at the inlet: 2.5 m/sRelative velocity at the outlet: -1.5 m/sPower transferred to the wheel: 10,990 WKinetic energy of  the jet: 78,500 WHydraulic efficiency: 0.14

Air flows through a cylindrical duct at a rate of 2.3 kg/s. Friction between air and the duct and friction within air can be neglected. The diameter of the duct is 10cm and the air temperature and pressure at the inlet are T₁ = 450 K and P₁ = 200 kPa. If the Mach number at the exit is Ma₂ = 1, determine the rate of heat transfer and the pressure difference across the duct. The constant pressure specific heat of air is Cp 1.005 kJ/kg.K. The gas constant of air is R = 0.287 kJ/kg-K and assume k = 1.4.

Answers

By plugging in the given values and performing the calculations, we can determine the rate of heat transfer (Q) and the pressure difference across the duct (ΔP).

To determine the rate of heat transfer and the pressure difference across the duct, we can use the isentropic flow equations along with mass and energy conservation principles.

First, we need to calculate the cross-sectional area of the duct, which can be obtained from the diameter:

A₁ = π * (d₁/2)²

Given the mass flow rate (ṁ) of 2.3 kg/s, we can calculate the velocity at the inlet (V₁):

V₁ = ṁ / (ρ₁ * A₁)

where ρ₁ is the density of air at the inlet, which can be calculated using the ideal gas equation:

ρ₁ = P₁ / (R * T₁)

Next, we need to determine the velocity at the exit (V₂) using the Mach number (Ma₂) and the speed of sound at the exit (a₂):

V₂ = Ma₂ * a₂

The speed of sound (a) can be calculated using:

a = sqrt(k * R * T)

Now, we can calculate the temperature at the exit (T₂) using the isentropic relation for temperature and Mach number:

T₂ = T₁ / (1 + ((k - 1) / 2) * Ma₂²)

Using the specific heat capacity at constant pressure (Cp), we can calculate the rate of heat transfer (Q):

Q = Cp * ṁ * (T₂ - T₁)

Finally, the pressure difference across the duct (ΔP) can be calculated using the isentropic relation for pressure and Mach number:

P₂ / P₁ = (1 + ((k - 1) / 2) * Ma₂²)^(k / (k - 1))

ΔP = P₂ - P₁ = P₁ * ((1 + ((k - 1) / 2) * Ma₂²)^(k / (k - 1)) - 1)

A. 324.80 mm2
B. 246.80 mm2
C. 446.80 mm2
D. 277.77 mm2

Answers

The cross-sectional dimension of the square key to be used is approximately 277.77 mm². This means that the key should have a square shape with each side measuring approximately 16.68 mm (sqrt(277.77)).

To determine the cross-sectional dimension of the square key, we can use the formula for bearing stress:

\[ \sigma = \frac{T}{d \cdot l} \]

where:

- σ is the bearing stress (in MPa)

- T is the torque (in N·m)

- d is the diameter of the shaft (in mm)

- l is the length of the key (in mm)

Rearranging the formula, we can solve for the cross-sectional area (A) of the square key:

\[ A = \frac{T}{\sigma \cdot l} \]

Plugging in the given values:

T = 2 kN·m = 2000 N·m

d = 40 mm

σ = 400 MPa

l = 30 mm

Calculating the cross-sectional area:

\[ A = \frac{2000}{400 \cdot 30} =  277.77 mm².

Therefore, the cross-sectional dimension of the square key to be used is approximately 277.77 mm². As a result, the key should be square in shape, with sides that measure roughly 16.68 mm (sqrt(277.77)).

Answers

The original diameter of the wheel is 105mm. The correct option is (a)

Given:

Distance between centers = 82.5 mm.

Transmission ratio, n = 1.75.Module, m = 3 mm.

Formula:

Transmission ratio (n) = (Diameter of Driven Gear/ Diameter of Driving Gear)

From this formula we can say that

Diameter of Driven Gear = Diameter of Driving Gear × Transmission ratio.

Diameter of Driving Gear = Distance between centers/ (m × π).Diameter of Driven Gear = Diameter of Driving Gear × n.

Substituting, Diameter of Driving Gear = Distance between centers/ (m × π)

Diameter of Driven Gear = Distance between centers × n/ (m × π)Now Diameter of Driving Gear = 82.5 mm/ (3 mm × 3.14) = 8.766 mm

Diameter of Driven Gear = Diameter of Driving Gear × n = 8.766 × 1.75 = 15.34 mm

Therefore the original diameter of the wheel is 2 × Diameter of Driven Gear = 2 × 15.34 mm = 30.68 mm ≈ 31 mm

Hence the option (c) 35mm is incorrect and the correct answer is (a) 105mm.

Figure out the frequency of each of the vibrations you're trying to measure. 2. Set the cutoff frequencies for each of your bandpass filters.

Answers

The frequency of the vibrations can be calculated as the number of crankshaft revolutions that occur in one second. Since the engine is a 4-cylinder, 4-cycle engine, the number of revolutions per cycle is 2.

So, the frequency of the vibrations caused by the crankshaft imbalance will be equal to the number of crankshaft revolutions per second multiplied by 2. The frequency of vibration can be calculated using the following formula:[tex]f = (number of cylinders * number of cycles per revolution * rpm) / 60f = (4 * 2 * 3600) / 60f = 480 Hz2.[/tex]

Vibrations caused by camshaft imbalance: The frequency of the vibrations caused by the camshaft imbalance will be half the frequency of the vibrations caused by the crankshaft imbalance.

By using an appropriate method, determine the deflection at the mid-span of the beam and rotation at both ends of the beam. Take Young’s modulus as 31 GPa. Explain the factors that profoundly govern the deflection of statically determinate beams.

Answers

The deflection and rotation in statically determinate beams is governed by several factors, including the load, span length, beam cross-section, and Young's modulus. To determine the deflection at the mid-span of the beam and the rotation at both ends of the beam, the following method can be used:

Step 1: Determine the reaction forces and moments: Start by calculating the reaction forces and moments at the beam's support. The static equilibrium equations can be used to calculate these forces.

Step 2: Calculate the slope at the ends:

Calculate the slope at each end of the beam by using the relation: M1 = (EI x d2y/dx2) at x = 0 (left end) M2 = (EI x d2y/dx2) at x = L (right end)where, M1 and M2 are the moments at the left and right ends, respectively,

E is Young's modulus, I is the moment of inertia of the beam cross-section, L is the span length, and dy/dx is the slope of the beam.

Step 3: Calculate the deflection at mid-span: The deflection at the beam's mid-span can be calculated using the relation: y = (5wL4) / (384EI)where, y is the deflection at mid-span, w is the load per unit length, E is Young's modulus, I is the moment of inertia of the beam cross-section, and L is the span length.

Factors that govern the deflection of statically determinate beams. The deflection of a statically determinate beam is governed by the following factors:

1. Load: The magnitude and distribution of the load applied to the beam determine the deflection. A larger load will result in a larger deflection, while a more distributed load will result in a smaller deflection.

2. Span length: The longer the span, the greater the deflection. This is because longer spans are more flexible than shorter ones.

3. Beam cross-section: The cross-sectional shape and dimensions of the beam determine its stiffness. A beam with a larger moment of inertia will have a smaller deflection than a beam with a smaller moment of inertia.

4. Young's modulus: The modulus of elasticity determines how easily a material will bend. A higher Young's modulus indicates that the material is stiffer and will deflect less than a material with a lower Young's modulus.

A conical tube is fixed vertically with its smaller end upwards and it forms a part of pipeline. The velocity at the smaller end is 4.5 m/s and at the large end 1.5 m/s. Length of conical tube is 1.5 m. The pressure at the upper end is equivalent to a head of 10 m of water. (i) Neglecting friction, determine the pressure at the lower end of the tube.

Answers

Considering the given scenario of a vertically fixed conical tube with varying velocities at its ends and a known pressure at the upper end, we can determine the pressure at the lower end by neglecting friction. The calculated value for the pressure at the lower end is missing.

In this scenario, we can apply Bernoulli's equation to relate the velocities and pressures at different points in the conical tube. Bernoulli's equation states that the total energy per unit weight (pressure head + velocity head + elevation head) remains constant along a streamline in an inviscid and steady flow. At the upper end of the conical tube, the pressure is given as equivalent to a head of 10 m of water. Let's denote this pressure as P1. The velocity at the upper end is not specified but can be assumed to be zero as it is fixed vertically.

At the lower end of the conical tube, the velocity is given as 1.5 m/s. Let's denote this velocity as V2. We need to determine the pressure at this point, denoted as P2. Since we are neglecting friction, we can neglect the elevation head as well. Thus, Bernoulli's equation can be simplified as:

P1 + (1/2) * ρ * V1^2 = P2 + (1/2) * ρ * V2^2

As the velocity at the upper end (V1) is assumed to be zero, the first term on the left-hand side becomes zero, simplifying the equation further:

0 = P2 + (1/2) * ρ * V2^2

By rearranging the equation, we can solve for P2, which will give us the pressure at the lower end of the conical tube.

2. A punching press makes 25 holes of 20 mm diameter per minute in a plate 15 mm thick. This causes variation in the speed of flywheel attached to press from 240 to 220 rpm. The punching operation takes 2 seconds per hole. Assuming 6 Nm of work is required to shear 1 mm2 of the area and frictional losses account for 15% of the work supplied for punching, determine (a) the power required to operate the punching press, and (b) the mass of flywheel with radius of gyration of 0.5 m.

Answers

(a) Power required to operate the punching press:

The energy required to punch a hole is given by:

Energy = Force x Distance

The force required to punch one hole is given by:

Force = Shearing stress x Area of hole

Shearing stress = Load/Area

Area = πd²/4

where d is the diameter of the hole

Now,

d = 20 mm

Area = π(20)²/4

= 314.16 mm²

Area in m² = 3.14 x 10⁻⁴ m²

Load = Shearing stress x Area

The thickness of the plate = 15 mm

The volume of the material punched out

= πd²/4 x thickness

= π(20)²/4 x 15 x 10⁻³

= 942.48 x 10⁻⁶ m³

The work done for punching one

hole = Load x Distance

Distance = thickness

= 15 x 10⁻³ m

Work done = Load x Distance

= Load x thickness

= 6 x 10⁹ x 942.48 x 10⁻⁶

= 5.6549 J

The punching operation takes 2 seconds per hole

Hence, the power required to operate the punching press = Work done/time taken

= 5.6549/2

= 2.8275 W

Therefore, the power required to operate the punching press is 2.8275 W.

(b) Mass of flywheel with the radius of gyration of 0.5 m:

Frictional losses account for 15% of the work supplied for punching.

Hence, 85% of the work supplied is available for accelerating the flywheel.

The kinetic energy of the fly

wheel = 1/2mv²

where m = mass of flywheel, and v = change in speed

Radius of gyration = 0.5 m

Change in speed

= (240 - 220)

= 20 rpm

Time is taken to punch

25 holes = 25 x 2

= 50 seconds

Work done to punch 25 holes = 25 x 5.6549

= 141.3725 J

Work done in accelerating flywheel = 85% of 141.3725

= 120.1666 J

The initial kinetic energy of the flywheel = 1/2mω₁²

The final kinetic energy of the flywheel = 1/2mω₂²

where ω₁ = initial angular velocity, and

ω₂ = final angular velocity

The change in kinetic energy = Work done in accelerating flywheel

1/2mω₂² - 1/2mω₁² = 120.1666ω₂² - ω₁² = 240.3333 ...(i)

Torque developed by the flywheel = Change in angular momentum/time taken= Iω₂ - Iω₁/Time taken

where I = mk² is the moment of inertia of the flywheel

k = radius of gyration

= 0.5 m

The angular velocity of the flywheel at the beginning of the process

= 2π(240/60)

= 25.1327 rad/s

The angular velocity of the flywheel at the end of the process

= 2π(220/60)

= 23.0319 rad/s

The time taken to punch

25 holes = 50 seconds

Now,

I = mk²

= m(0.5)²

= 0.25m

Let T be the torque developed by the flywheel.

T = (Iω₂ - Iω₁)/Time taken

T = (0.25m(23.0319) - 0.25m(25.1327))/50

T = -0.0021m

The negative sign indicates that the torque acts in the opposite direction of the flywheel's motion.

Now, the work done in accelerating the flywheel

= Tθ

= T x 2π

= -0.0132m Joules

Hence, work done in accelerating the flywheel

= 120.1666 Joules-0.0132m

= 120.1666Jm

= 120.1666/-0.0132

= 9103.35 g

≈ 9.1 kg

Therefore, the mass of the flywheel with radius of gyration of 0.5 m is 9.1 kg.

We cannot conclude about the system stability. O. The system is stable. O. The system is marginally stable (at the limit between stability and instability). O. The system is unstable.

Answers

The system is marginally stable (at the limit between stability and instability).

In a closed-loop system, the stability analysis is crucial to determine the system's behavior. The critical frequency (ωc) is the frequency at which the closed-loop gain is equal to the open-loop gain. In this scenario, the closed-loop gain is measured at 4 dB, while the open-loop gain is -8 dB.

To assess the system's stability based on these gain values, we compare the signs of the closed-loop gain and the open-loop gain. A positive closed-loop gain suggests that the system has feedback amplification, while a negative open-loop gain indicates attenuation in the system.

Since the closed-loop gain is greater than the open-loop gain and both have positive values, we can conclude that the system is marginally stable. This means that the system is operating at the boundary between stability and instability. Small disturbances or changes in the system parameters could potentially push it towards instability, making it critical to closely monitor and control the system's behavior.

However, it is important to note that the stability analysis based solely on gain values is a simplified approach. Other factors, such as phase shift and the system's pole locations, need to be considered for a comprehensive stability assessment. Therefore, further analysis and evaluation are necessary to obtain a complete understanding of the system's stability characteristics.

Answers

The network output per kg of steam:To calculate the network output per kg of steam, we need to determine the specific enthalpy at various points in the cycle and then calculate the difference.

State 1: Steam at 20 bar, 360 °C

Using steam tables or other thermodynamic properties, we can find the specific enthalpy at state 1. Let's denote it as h1.

State 2: Steam expanded to 0.08 bar

The steam is expanded in the turbine, and we need to find the specific enthalpy at state 2, denoted as h2.

State 3: Condensed to saturated liquid water

The steam enters the condenser and is condensed to saturated liquid water. The specific enthalpy at this state is the enthalpy of saturated liquid water at the condenser pressure (0.08 bar). Let's denote it as h3.

State 4: Water pumped back to the boiler

The water is pumped back to the boiler, and we need to find the specific enthalpy at state 4, denoted as h4.

Now, the network output per kg of steam is given by:

Network output = (h1 - h2) - (h4 - h3)

The cycle efficiency:The cycle efficiency is the ratio of the network output to the heat input. Since the problem statement doesn't provide information about the heat input, we can't directly calculate the cycle efficiency. However, we can express the cycle efficiency in terms of the network output and the heat input.

Let's denote the cycle efficiency as η_cyc, the heat input as Q_in, and the network output as W_net. The cycle efficiency can be calculated using the following formula:

η_cyc = W_net / Q_in

Now, let's calculate the percentage reduction in the network and cycle efficiency due to the efficiencies of the turbine and the pump.

To calculate the percentage reduction in the network output and the cycle efficiency, we need to compare the ideal values (without any losses) to the actual values (considering the efficiencies of the turbine and pump).

The ideal network output per kg of steam (W_net_ideal) can be calculated as:

W_net_ideal = (h1 - h2) - (h4 - h3)

The actual network output per kg of steam (W_net_actual) can be calculated as:

W_net_actual = η_turbine * (h1 - h2) - η_pump * (h4 - h3)

The percentage reduction in the network output can be calculated as:

Percentage reduction in network output = ((W_net_ideal - W_net_actual) / W_net_ideal) * 100

Similarly, the percentage reduction in the cycle efficiency can be calculated as:

Percentage reduction in cycle efficiency = ((η_cyc_ideal - η_cyc_actual) / η_cyc_ideal) * 100

The T-S diagram of the cycle with respect to the saturation lines helps visualize the thermodynamic process and identify the states and paths of the working fluid. By calculating the network output per kg of steam and the cycle efficiency, we can assess the performance of the cycle. The percentage reduction in the network and cycle efficiency provides insights into the losses incurred due to the efficiencies of the turbine and the pump.

A new greenfield area developer has approached your company to design a passive optical network (PON) to serve a new residential area with a population density of 64 households. After discussion with their management team, they have decided to go with XGPON2 standard which is based on TDM-PON with a downlink transmission able to support 10 Gb/s. Assuming that all the 64 households will be served under this new PON, your company is consulted to design this network. Given below are the known parameters and specifications that may help with the design of the PON. Downlink wavelength window = 1550 nm Bit error-rate 10-15 Bit-rate = 10 Gb/s Transmitter optical power = 0 dBm 1:32 splitters are available with a loss of 15 dB per port 1:2 splitters are available with a loss of 3 dB per port Feeder fibre length = 12 km Longest drop fibre length = 4 km Put aside a total system margin of 3 dB for maintenance, ageing, repair, etc Connector losses of 1 dB each at the receiver and transmitter Splice losses are negligible a. Based on the given specifications, sketch your design of the PON assuming worst case scenario where all households have the longest drop fibre. (3 marks) b. What is the bit rate per household? (1 marks) c. Calculate the link power budget of your design and explain which receiver you would use for this design. (7 marks) d. Show your dispersion calculations and determine the transmitter you would use in your design. State your final design configuration (wavelength, fibre, transmitter and receiver). (4 marks) e. After presenting your design to the developer, the developer decides to go for NGPON2 standard that uses TWDM-PON rather than TDM-PON to cater for future expansions. Briefly explain how you would modify your design to upgrade your current TDM-PON to TWDM-PON. Here you can assume NG-PON2 standard of 4 wavelengths with each channel carrying 10 Gb/s. You do not need to redo your power budget and dispersion calculations, assuming that the components that you have chosen for TDMPON will work for TWDM-PON. Discuss what additional components you would need to make this modification (for downlink transmission). Also discuss how you would implement uplink for the TWDM-PON. Sketch your modified design for downlink only. d- Label the following organisms as prokaryotes or eukaryotes Organism Tiger Fungi Pseudomonas bacteria Algae E.
