The gear is transmitting approximately 1.336 hp.

To calculate the power transmitted by the gear, we can use the formula:

Power (in hp) = (Torque × Speed) / 5252

First, let's calculate the torque. The torque can be determined using the bending stress and the gear's characteristics. The formula for torque is:

Torque = (Bending stress × Module × Face width) / (Diametral pitch × Velocity factor)

In this case, the number of teeth (N) is given as 20, and the diametral pitch (P) is given as 16/in. To find the module (M), we can use the formula:

Module = 25.4 / Diametral pitch

Substituting the given values, we find the module to be 1.5875. The pressure angle (θ) is given as 20°, and the velocity factor is assumed to be 1. The face width can be estimated based on the gear's application.

Now, let's calculate the torque:

Torque = (20 ksi × 1.5875 × face width) / (16/in × 1)

Next, we need to convert the torque from inch-pounds to foot-pounds, as the speed is given in revolutions per minute (rpm) and we want the final power result in horsepower (hp). The conversion is:

Torque (in foot-pounds) = Torque (in inch-pounds) / 12

After obtaining the torque in foot-pounds, we can calculate the power:

Power (in hp) = (Torque (in foot-pounds) × Speed (in rpm)) / 5252

Substituting the given values, we find the power to be approximately 1.336 hp.

To design a parallel bandreject filter with the given specifications, we can use an RLC circuit. Here's how you can calculate the resistor and inductor values:

Given:

Center frequency (f0) = 1000 rad/s

Bandwidth (B) = 4000 rad/s

Passband gain (Av) = 6

Capacitor value (C) = 0.2 μF

Calculate the resistor value (R):

Use the formula R = Av / (B * C)

R = 6 / (4000 * 0.2 * 10^(-6)) = 7.5 kΩ

Calculate the inductor value (L):

Use the formula L = 1 / (B * C)

L = 1 / (4000 * 0.2 * 10^(-6)) = 12.5 H

So, for the parallel bandreject filter with a center frequency of 1000 rad/s, a bandwidth of 4000 rad/s, and a passband gain of 6, you would use a resistor value of 7.5 kΩ and an inductor value of 12.5 H.

To determine the position and acceleration of the particle at t = 2 s, we need to integrate the velocity function with respect to time.

Given:

Velocity function: v = 80 m/s

Initial condition: v₀ = 0 (particle released from rest)

To find the position function, we integrate the velocity function:

x(t) = ∫v(t) dt

      = ∫(80) dt

      = 80t + C

To find the value of the constant C, we use the initial condition x₀ = 0 (particle released from rest):

x₀ = 80(0) + C

C = 0

So, the position function becomes:

x(t) = 80t

To find the acceleration, we differentiate the velocity function with respect to time:

a(t) = d(v(t))/dt

       = d(80)/dt

       = 0

Therefore, the position of the particle at t = 2 s is x(2) = 80(2) = 160 m, and the acceleration at t = 2 s is a(2) = 0 m/s².

B) The maximum theoretical efficiency of the cycle is = 0.75 or 75%

C)  The entropy generation rate of the cycle is 1.85 x  10⁻³ KW/K.

Given Data:

             Power generated, W = 4 kW

             Heat rejected, Qr = 6 kW

            Source temperature, T1 = 800°C

           Sink temperature, T2 = 200°C

A) Thermal efficiency of the cycle is given as the ratio of net work output to the heat supplied to the system.

The thermal efficiency of the cycle is given by:

                                     η = (W/Qh)

                                        = (Qh - Qr)/Qh

Where, Qh is the heat absorbed or heat supplied to the system.

Hence, the thermal efficiency of the cycle is:

                                   η = (Qh - Qr)/Qh

                                  η = (4 - 6)/4

                                   ηmax = (T1 - T2)/T1

Where T1 is the temperature of the source

           T2 is the temperature of the sink.

Therefore, the maximum theoretical efficiency of the cycle is:

                                  ηmax = (T1 - T2)/T1

                                  ηmax = (800 - 200)/800

                                   ηmax = 0.75 or 75%

C) Entropy generation rate of the cycle is given by the following formula:

                                    ΔSgen = Qr/T2 - Qh/T1

Where, Qh is the heat absorbed or heat supplied to the system

            Qr is the heat rejected by the system.

Therefore, the entropy generation rate of the cycle is:

                                ΔSgen = Qr/T2 - Qh/T1

                                ΔSgen = 6/473 - 4/1073

                                ΔSgen = 1.85 x 10⁻³ KW/K

Thus, the entropy generation rate of the cycle is 1.85 x  10⁻³ KW/K.

The final temperature of steam in the tank is 375/V1°C, and the final mass of steam in the tank is 1041.26 V1 kg.

The given problem is related to the thermodynamics of a closed system. Here, we are given an insulated, rigid tank whose volume is 0.5 m³, and it is connected to a large vessel holding steam at 40 bar and 400°C. The tank is initially evacuated. The valve is opened only as long as required to fill the tank with steam to a pressure of 30 bar. Our objective is to determine the final temperature of the steam in the tank and the final mass of the steam in the tank. We will use the following formula to solve the problem:

PV = mRT

where P is the pressure, V is the volume, m is the mass, R is the gas constant, and T is the temperature.

The gas constant R = 0.287 kJ/kg K for dry air. Here, we assume steam to behave as an ideal gas because it is at high temperature and pressure. Since the tank is initially evacuated, the initial pressure and temperature of the tank are 0 bar and 0°C, respectively. The final pressure of the steam in the tank is 30 bar. Let's find the final temperature of the steam in the tank as follows:

P1V1/T1 = P2V2/T2

whereP1 = 40 bar, V1 = ?, T1 = 400°CP2 = 30 bar, V2 = 0.5 m³, T2 = ?

Rearranging the above formula, we get:

T2 = P2V2T1/P1V1T2 = 30 × 0.5 × 400/(40 × V1)

T2 = 375/V1

The final temperature of steam in the tank is 375/V1°C.

Now let's find the final mass of the steam in the tank as follows:

m = PV/RT

where P = 30 bar, V = 0.5 m³, T = 375/V1R = 0.287 kJ/kg K for dry air

We know that the mass of steam is equal to the mass of water in the tank since all the water in the tank has converted into steam. The density of water at 30 bar is 30.56 kg/m³. Let's find the volume of water required to fill the tank as follows:

V_water = m_water/density = 0.5/30.56 = 0.0164 m³

where m_water is the mass of water required to fill the tank. Since all the water in the tank has converted into steam, the final mass of steam in the tank is equal to m_water. Let's find the final mass of steam in the tank as follows:

m = PV/RT = 30 × 10^5 × 0.5/(0.287 × 375/V1) = 1041.26 V1 kg

The final mass of steam in the tank is 1041.26 V1 kg.

Therefore, the final temperature of steam in the tank is 375/V1°C, and the final mass of steam in the tank is 1041.26 V1 kg.

In a large parallel plate capacitor with a hemispherical bulge on the grounded plate, the potential everywhere inside the capacitor can be obtained by solving the Laplace's equation.

The Laplace's equation is a second-order partial differential equation that describes the behavior of the electric potential.

It is given by the equation ∇2V = 0, where V is the electric potential and ∇2 is the Laplacian operator.

The Laplace's equation can be solved using the method of separation of variables.

We can assume that the electric potential is of the form

V(x,y,z) = X(x)Y(y)Z(z),

where x, y, and z are the coordinates of the capacitor.

Substituting this expression into the Laplace's equation, we get:

X''/X + Y''/Y + Z''/Z = 0.

Since the left-hand side of this equation depends only on x, y, and z separately, we can write it as

X''/X + Y''/Y = -Z''/Z = λ2,

where λ is a constant. Solving these equations for X(x), Y(y), and Z(z), we get:

X(x) = A cosh(μx) + B sinh(μx)

Y(y) = C cos(nπy/b) + D sin(nπy/b)

Z(z) = E cosh(λz) + F sinh(λz),

where μ = a/√(b2-a2), n = 1, 2, 3, ..., and E and F are constants that depend on the boundary conditions.

The potential everywhere inside the capacitor is therefore given by:

V(x,y,z) = ∑ Anm cosh(μmx) sin(nπy/b) sinh(λmz),

where Anm are constants that depend on the boundary conditions.

To find the surface charge density on the flat portion of the grounded plate, we can use the boundary condition that the electric field is normal to the surface of the plate.

Since the electric field is given by

E = -∇V,

where V is the electric potential, the normal component of the electric field is given by

E·n = -∂V/∂n,

where n is the unit normal vector to the surface of the plate.

The surface charge density is then given by

σ = -ε0 E·n,

where ε0 is the permittivity of free space.

To find the surface charge density on the bulge, we can use the same method and the boundary condition that the electric field is normal to the surface of the bulge.

m = mass flow rate of gas in kg/s;

cp = specific heat capacity of gas in kJ/kg K;

T₁ = Inlet temperature of the gas in K;

T₂ = Exit temperature of the gas in K;

R = Gas constant in kJ/kg K; and,

P₁ = Inlet pressure of the gas in kPa; and

P₂ = Exit pressure of the gas in kPa.

Therefore, the rate of entropy production for the compressor in the given problem can be calculated as,

Entropy production rate (kW/K) = (8.204 kW - Heat Transfer) / [10 kg/min (cp ln(256.85/26.85) - R ln(607/100))]

Where,

cp = 1.013 kJ/kg K,

R = 0.287 kJ/kg K.

Therefore,

Entropy production rate (kW/K) = (8.204 kW - Heat Transfer) / 469.79

Heat Transfer = m (cp (T₂ - T₁)) where,

m = 10 kg/min and

T2 = 348.5°C = 621.65 K.

Heat Transfer = 10 kg/min (1.013 kJ/kg K) (621.65 K - 256.85 K).

Heat Transfer = 285.354 kW

Entropy production rate (kW/K) = (8.204 kW - 285.354 kW) / 469.79 = -0.570737 kW/K (six decimal places).

Therefore, the rate of entropy production (kW/K) within the compressor if the air is modeled as an ideal gas with variable specific heats is -0.570737 kW/K.

(i) Maslow's hierarchy of needs is a theory of human needs that helps to understand the various factors that influence the motivation of individuals.

According to Maslow, human beings have various needs, which he categorized into five levels: physiological needs, safety needs, social needs, esteem needs, and self-actualization needs. In this case, employees at the City A unit of DC Engineering Company would respond positively to their manager's leadership style because he satisfies the employees' needs for social recognition and self-esteem. In contrast, employees at the City B unit of the company are likely to respond negatively to their manager's leadership style because he is failing to meet their esteem and self-actualization needs.

(ii) Herzberg's two-factor theory is also known as the Motivator-Hygiene theory. Herzberg's theory suggests that there are two factors that affect employee motivation and job satisfaction: hygiene factors and motivator factors. Hygiene factors include working conditions, salary, job security, and company policies. Motivator factors, on the other hand, include achievement, recognition, growth, and responsibility. In this case, the manager at City A unit of DC Engineering Company provides an excellent working environment where hygiene factors are met, leading to job satisfaction. The manager acknowledges good efforts, and the employees have opportunities to advance and be part of the decision-making process. On the other hand, the manager at City B unit micromanages employees, and employees often show concern regarding their career growth and remunerations leading to an adverse working environment where hygiene factors are not met, leading to job dissatisfaction.

(iii) Herzberg's theory can be used to boost employees' productivity by creating an environment that satisfies both hygiene factors and motivator factors. Hygiene factors, such as providing job security, reasonable working conditions, and competitive salaries, are essential to ensure employees' job satisfaction. Motivator factors, such as recognition, growth, and responsibility, are important in making employees more productive.

(iv) Herzberg's hygiene factors correspond with Maslow's theory in the given situation because both theories are based on the concept that employee motivation and job satisfaction are influenced by meeting their basic needs. Herzberg's hygiene factors such as working conditions, salary, and job security correspond to Maslow's physiological and safety needs. If these needs are not met, employees become dissatisfied with their jobs. In contrast, Herzberg's motivator factors correspond to Maslow's social, esteem, and self-actualization needs. If these needs are met, employees become motivated and productive.

(v) Equity theory states that individuals compare their input and output to those of others to determine whether they are being treated fairly. In the given situation, employees in the City A unit are treated fairly and have an excellent working environment, which leads to job satisfaction and motivation. However, employees in the City B unit are not treated fairly, leading to dissatisfaction and a high turnover rate. Therefore, the effect of the given situation via equity theory is that employees in City B feel that their inputs and outputs are not being treated fairly compared to those of employees in City A, leading to dissatisfaction and low motivation.

To answer your questions, let's consider the context of fluid mechanics and boundary layers:

Assumptions in the solution: In fluid mechanics, various assumptions are often made to simplify the analysis and mathematical modeling of fluid flow. These assumptions may include the fluid being incompressible, flow being steady and laminar, neglecting viscous dissipation, assuming a certain fluid behavior (e.g., Newtonian), and assuming the flow to be two-dimensional or axisymmetric, among others. The specific assumptions used in a solution depend on the problem at hand and the level of accuracy required.

Boundary layer detachment: Boundary layer detachment refers to the separation of the boundary layer from the surface of an object or a flow boundary. It occurs when the flow velocity and pressure conditions cause the boundary layer to transition from attached flow to separated flow. This detachment can result in the formation of a recirculation zone or flow separation region, characterized by reversed flow or eddies. Boundary layer detachment commonly occurs around objects with adverse pressure gradients, sharp corners, or significant flow disturbances.

Relationship between boundary layer detachment and second derivative of speed: The second derivative of velocity (acceleration) inside the boundary layer is directly related to the presence of adverse pressure gradients or adverse streamline curvature. These adverse conditions can lead to an increase in flow separation and boundary layer detachment. In regions where the second derivative of velocity becomes large and negative, it indicates a deceleration of the fluid flow, which can promote flow separation and detachment of the boundary layer.

Velocity of steam at nozzle outlet, V1 = 660 m/s

Angle of outlet of steam from the nozzle, α1 = 17°

Blades outlet angle of first moving row of turbine, β2 = 18°

Blades outlet angle of second moving row of turbine, β2 = 36°

Blades outlet angle of the row of fixed blades, βf = 22°

Mean radius of the blade wheel, r = 155 mm = 0.155 m

Rotational speed of the blade wheel, N = 4000 rpm

Steam flow rate, m = 80 kg/min

Reduction in steam velocity over all the blades, i.e., (V1 − V2)/V1 = 10% = 0.1

Scale used, 1 mm = 5 m/s (for drawing velocity diagrams)

The length of the blade in the first and second rows of the turbine blades can be determined using the velocity diagram.

Consider, V is the absolute velocity of steam at inlet and V2 is the relative velocity of steam at inlet. Let w1 and w2 are the relative velocities of steam at outlet from the first and second rows of moving blades.

Hence, using the law of cosines, we get

V2² = w1² + V1² – 2w1V1 cos (α1 – β1)

For the first row of blades, β1 = 18°V2² = w1² + 660² – 2 × 660w1 cos (17° – 18°)

w1 = 680.62 m/s

The length of the velocity diagram is proportional to w1, i.e., 680.62/5 = 136.124 mm

Similarly, for the second row of moving blades, β1 = 36°V2² = w2² + 660² – 2 × 660w2 cos (17° – 36°)

w2 = 690.99 m/s

The length of the velocity diagram is proportional to w2, i.e., 690.99/5 = 138.198 mm

Let w1′ and w2′ be the relative velocities of steam at outlet from the first and second rows of blades, respectively.Using the law of cosines, we get

V2² = w1′² + V1² – 2w1′V1 cos (α1 – βf)

For the row of fixed blades, β1 = 22°

V2² = w1′² + 660² – 2 × 660w1′ cos (17° – 22°)

w1′ = 695.32 m/s

The length of the velocity diagram is proportional to w1′, i.e., 695.32/5 = 139.064 mm

The axial thrust on the shaft is given by difference between axial forces acting on the first and second moving row of blades.

Hence,Total axial thrust on the shaft = (m × (w1 sin β1 + w2 sin β2)) − (m × w1′ sin βf) = (80/60) × (680.62 sin 18° + 690.99 sin 36°) – (80/60) × 695.32 sin 22° = 286.4 N

The tangential force acting on each blade can be given by,f = (m (w1 − w1′)) / N

Length of the blade wheel = 2πr = 2 × 3.14 × 0.155 = 0.973 m

Total tangential force on the blade = f × length of blade wheel = ((80/60) × (680.62 − 695.32)) / 4000 × 0.973 = −7.874 N (negative sign implies the direction of force is opposite to the direction of wheel rotation)

Power developed by the turbine can be given by,P = m(w1V1 − w2V2) / 1000 = 80 × (680.62 × 660 − 690.99 × 656.05) / 1000 = 541.23 kW

The blade efficiency can be given by,ηb = (actual work done / work done if steam is entirely used in nozzle) = ((w1V1 − w2V2) / (w1V1 − V2)) = 84.5%

The average blade velocity can be determined by,πDN = 2πNr

The production cost per 1000 kg steam in a steam plant when the evaporation rate is 7.2 kg steam per kg coal is $18.03. This is obtained as follows;

Step-by-step explanation:

The steam produced from the combustion of coal in a steam plant can be evaluated by first finding the amount of steam generated per kg of coal burned. This is called the evaporation rate.The evaporation rate is given as 7.2 kg steam per kg coal.The cost of coal is given as $8.00 per ton.The steam plant has an average steam production of 14,500 kg per hr.Annual operational cost exclusive of coal is $15,000.The initial cost of plant is $150,000.The life of the steam plant is 20 years.

The interest on borrowed capital is 4% while the interest on the sinking fund is 3%.To find the cost of steam production per 1000 kg, the following calculations are made;

Total amount of steam produced in one year = 14,500 * 24 * 365 = 126,540,000 kg

Annual coal consumption = 126,540,000 / 7.2 = 17,541,666.67 kg

Total cost of coal in one year = (17,541,666.67 / 1000) * $8.00 = $140,333.33

Total cost of operation per year = $140,333.33 + $15,000 = $155,333.33

Annual equivalent charge = AEC = 1 + i/n - 1/(1+i/n)^n*t

Where i = interest n = number of years for which the sum is invest

dt = total life of the investment AEC = 1 + 0.04/1 - 1/(1+0.04/1)^(1*20) = 1.7487

Annual equivalent disbursement = AED = S / a

Where S = initial cost of plant + sum of annual cost (AEC) for n y

earsa = annuity factor obtained from the tables

.AED = $150,000 / 3.8879 = $38,595.69

Annual sinking fund = AS = AED * i / (1 - 1/(1+i/n)^n*t)AS = $38,595.69 * 0.03 / (1 - 1/(1+0.03/1)^(1*20)) = $1,596.51

Total annual cost of the steam plant

= $155,333.33 + $1,596.51

= $156,929.84

Cost of steam production per 1000 kg = 1000 / (126,540,000 / 14,500) * $156,929.84 = $18.03Therefore, the cost of steam production per 1000 kg is $18.03.

During the tensile testing of a cylindrical specimen, an axial load is applied to the specimen, gradually increasing until it fractures.

The test helps determine the material's mechanical properties. Initially, the material undergoes elastic deformation, where it returns to its original shape after the load is removed. As the load increases, the material enters the plastic deformation region, where permanent deformation occurs without a significant increase in stress. The material may start to neck down, reducing its cross-sectional area. Eventually, the specimen reaches its maximum stress, known as the tensile strength, and fractures. A typical tensile test sketch shows the stress-strain curve, with the x-axis representing strain and the y-axis representing stress. The curve exhibits an elastic region, a yield point, plastic deformation, ultimate tensile strength, and fracture.
