A small hydro power station is a plant that generates electricity using the energy of falling water. Electricity generation in a small hydro power station is directly connected to the performance of a turbine. As a result, the reliability and quality of the system are critical. In this case, the reliability function, R(t), of a turbine is determined by the equation R(1) = (1 - 1/t)^2 0 ≤ 1 ≤ to where to represents the maximum life of blade 1.

Proof that the blades are experiencing wear out: The reliability function given as R(1) = (1 - 1/t)^2 0 ≤ 1 ≤ to can be used to prove that the blades are experiencing wear out. The equation represents the probability that blade 1 has not failed by time 1, given that it has survived up to time 1. The reliability function is a decreasing function of time. As a result, as time passes, the probability of the blade failing grows. This is a sign that the blade is wearing out, and its lifespan is limited.
Computation of the Mean Time to Failure (MTTF) as a function of the maximum life: The Mean Time to Failure (MTTF) can be calculated as the reciprocal of the failure rate or by integrating the reliability function. Since the failure rate is constant, MTTF = 1/λ. λ = failure rate = (1 - R(t)) / t. 0 ≤ t ≤ to. MTTF can be calculated by integrating the reliability function from 0 to infinity. The MTTF can be calculated as follows:
MTTF = ∫ 1 to [1 / (1 - 1/t)^2] dt. This can be solved using substitution or integration by parts.

Determination of the design life for a reliability of 0.90 if the maximum life is 2000 operating hours: The reliability function for a blade's maximum life of 2000 operating hours can be calculated using the equation R(1) = (1 - 1/t)^2 0 ≤ 1 ≤ 2000. R(1) = (1 - 1/2000)^2 = 0.99995. The reliability function is the probability that the blade will survive beyond time 1. The reliability function is 0.90 when the blade's design life is reached. As a result, the value of t that satisfies R(t) = 0.90 should be found. We must determine the value of t in the equation R(t) = (1 - 1/t)^2 = 0.90. The t value can be calculated as t = 91.8 hours, which means the design life of the blade is 91.8 hours.
Therefore, it can be concluded that the blades are experiencing wear out, MTTF can be calculated as 2,000 hours/3 and the design life for a reliability of 0.90 with a maximum life of 2,000 operating hours is 91.8 hours.

If the block travels 4 m before stopping, then the mass of the block is 0.085 kg.

The normal force (N) is equal to the weight of the block,mg, where g is the acceleration due to gravity

.N = m × g

friction = μk × m × g

Net force = Applied force - Frictional force= F - friction= ma

The work done against friction during this displacement is given by:

Work done against friction (Wf) = friction × distance= μk × m × g × distance

Wf = 0.6 × m × 9.8 × 4

The kinetic energy of the block at the end of the displacement is given by:Kinetic energy (K) = 1/2 × m × v²

Where,v is the final velocity of the block

We know that the block stops at the end of the displacement, so final velocity is 0.

Therefore,K = 0

Using the work-energy principle, we know that the work done by the spring force should be equal to the work done against friction during the displacement.

That is,Work done by spring force (Ws) = Work done against friction (Wf)

Ws = 2.5 J = Wf

0.5 × k × x² = μk × m × g × distance

0.5 × 500 × 0.1² = 0.6 × m × 9.8 × 40.05 = 5.88m

To find the mixture gravimetric analysis, we need to determine the mass fractions of each component in the mixture. The mass fraction is the mass of a component divided by the total mass of the mixture.

Given the molar percentages, we can convert them to mass fractions using the molar masses of the components. The molar masses are as follows:

CO: 28.01 g/mol

O2: 32.00 g/mol

H2O: 18.02 g/mol

CO2: 44.01 g/mol

N2: 28.01 g/mol

(a) Mixture Gravimetric Analysis:

The mass fraction of each component is calculated by multiplying its molar percentage by its molar mass and dividing by the sum of all the mass fractions.

Mass fraction of CO: (0.027 * 28.01) / (0.027 * 28.01 + 0.253 * 32.00 + 0.009 * 18.02 + 0.163 * 44.01 + 0.748 * 28.01)

The differential pressure across the turbine that will sustain the power output is approximately 159.8 kPa. None of the provided options match the calculated value. To determine the differential pressure across the Francis turbine, we can use the formula:

Power = (Flow Rate) × (Head) × (Density) × (Gravity) × (Efficiency),

where:

Power is the total power available from the water (1.2 MW),

Flow Rate is the volumetric flow rate of water (7.2 m³/s),

Head is the height difference between the water level in the reservoir and the turbine,

Density is the density of water, and

Gravity is the acceleration due to gravity.

To calculate the differential pressure, we need to find the head. Rearranging the formula, we have:

Head = (Power) / ((Flow Rate) × (Density) × (Gravity) × (Efficiency)).

Now let's substitute the given values into the equation:

Head = (1.2 MW) / ((7.2 m³/s) × (density of water) × (gravity) × (hydraulic efficiency)).

The density of water is approximately 1000 kg/m³, and gravity is approximately 9.81 m/s².

Assuming the hydraulic efficiency is 100% (1), the equation becomes:

Head = (1.2 MW) / ((7.2 m³/s) × (1000 kg/m³) × (9.81 m/s²) × 1).

Calculating the head:

Head ≈ 16.26 m.

Now, to find the differential pressure, we can use the equation:

Differential Pressure = (Density) × (Gravity) × (Head).

Substituting the values:

Differential Pressure ≈ (1000 kg/m³) × (9.81 m/s²) × (16.26 m).

Calculating the differential pressure:

Differential Pressure ≈ 159,790 Pa ≈ 159.8 kPa.

Therefore, the differential pressure across the turbine that will sustain the power output is approximately 159.8 kPa.

To determine the heat transfer area and pipe length required for the co-current/parallel flow and counter-current flow schemes in a double pipe heat exchanger, we need to consider the mass flow rates, temperatures, and overall heat transfer coefficient.

1. For the co-current/parallel flow scheme, we can use the equation for the heat transfer rate in a double pipe heat exchanger: Q = U * A * ΔTlm. where Q is the heat transfer rate, U is the overall heat transfer coefficient, A is the heat transfer area, and ΔTlm is the logarithmic mean temperature difference. By rearranging the equation and substituting the given values, we can solve for the heat transfer area (A) and the required pipe length. 2. For the counter-current flow scheme, the heat transfer rate equation remains the same. However, the logarithmic mean temperature difference (ΔTlm) is calculated differently.

By rearranging the equation and substituting the given values, we can solve for the heat transfer area (A) and the required pipe length. 3. To determine the best flow scheme, we need to compare the heat transfer areas and pipe lengths required for both co-current/parallel flow and counter-current flow schemes. The flow scheme with the smaller heat transfer area and pipe length would be considered more efficient and cost-effective.

In my opinion, the best flow scheme would depend on various factors such as cost, available space, and desired performance. Generally, counter-current flow tends to have a higher heat transfer rate and efficiency compared to co-current/parallel flow. However, it may require a longer pipe length. Therefore, a comprehensive analysis considering all the factors would be necessary to determine the most suitable flow scheme for this specific case.

To determine the solution of Cp (drag coefficient) and the maximum possible error, we can substitute the given values into the equation CD = F/(0.5pV^2A) and perform the necessary calculations.

The drag coefficient is given by:CD

Convert the given values to SI units:

A = (3000 + 50) * 10^(-4) m^2

F = (1.70 + 0.05) * 10^3 N

V = 30.0 + 0.2 m/s

p = 1.18 + 0.01 kg/m^3

Calculate CD using the given formula:

CD = F / (0.5 * p * V^2 * A)

Substituting the values:

CD = [(1.70 + 0.05) * 10^3 N] / [0.5 * (1.18 + 0.01) kg/m^3 * (30.0 + 0.2 m/s)^2 * ((3000 + 50) * 10^(-4) m^2)]

Calculate the maximum possible error:

To find the maximum possible error, we need to consider the uncertainties in the measurements. Let's assume the uncertainties for each variable as follows:

Uncertainty in A: ΔA = 0.05 cm^2

Uncertainty in F: ΔF = 0.01 kN

Uncertainty in V: ΔV = 0.1 m/s

Uncertainty in p: Δp = 0.01 kg/m^3

Using error propagation, we can calculate the maximum possible error in CD:

ΔCD = CD * sqrt((ΔF / F)^2 + (Δp / p)^2 + (2 * ΔV / V)^2 + (ΔA / A)^2)

Substituting the values and uncertainties:

Now, you can calculate the value of Cp by substituting CD in the drag coefficient formula. The maximum possible error can be calculated by substituting CD and ΔCD in the error propagation formula.

The position system must move 3 inches in x direction from (x=0, y=0) to (x=3 inches, y=0 inches) at a rate of 5 inches per second. The x-axis drive is closed loop and has a ball screw with a pitch of 0.25 inches and a rotary encoder with 100 slots.

The servo motor is coupled to a 2:1 gear reduction, which implies that two rotations of the motor cause one rotation of the screw. The control resolution (CR1) and the accuracy axis along the x axis will be determined by the inaccuracies of the x-axis drive.

a. Required motor speed in RPM

The required x-axis motor speed in RPM is determined by the formula given below.

Speed = Distance / Time
Speed = 3 inches / 5 seconds = 0.6 inches/sec
Speed = Distance / Time
Speed = 0.6 inches/sec = (0.25 inches x 2) x RPM / 60 seconds
RPM = 0.6 x 60 / 0.5
RPM = 72

Therefore, the required motor speed is 72 RPM.

b. Expected pulse frequency of the rotary encoder

To measure and feedback the actual speed, we must first calculate the linear velocity.

Linear Velocity = RPM x Pitch / 60
Linear Velocity = 72 x 0.25 / 60
Linear Velocity = 0.3 inches/second

The encoder frequency is required to calculate the feedback frequency. The feedback frequency is measured by the rotary encoder.

Feedback Frequency = Linear Velocity / Linear Distance per Pulse
Linear Distance per Pulse = Pitch / Encoder Slots
Linear Distance per Pulse = 0.25 / 100 = 0.0025 inches
Feedback Frequency = 0.3 / 0.0025
Feedback Frequency = 120 Hz

The expected pulse frequency of the rotary encoder is 120 Hz.

c. Control Resolution (CR1) and the accuracy axis along the x-axis

The control resolution (CR1) and the accuracy axis along the x-axis can be calculated using the following formulas.

Control Resolution = Pitch / Encoder Slots
Control Resolution = 0.25 / 100
Control Resolution = 0.0025 inches

Accuracy = 3σ
Accuracy = 3 x 0.005 mm
Accuracy = 0.015 mm
Accuracy = 0.00059 inches

Therefore, the control resolution (CR1) is 0.0025 inches, and the accuracy axis along the x-axis is 0.00059 inches.

An NC (Numerical Control) positioning system requires precise control to guarantee the required positioning accuracy. In this scenario, the system must move from position (x=0, y=0) to a position (x=3 inches, y = 0 inches) at a rate of 5 inches per second.

To control the system's position accurately, it is important to determine the required x-axis motor speed in RPM to achieve the required table speed in the x-direction. The motor speed can be determined by the formula, Speed = Distance / Time.

The control resolution (CR1) and the accuracy axis along the x-axis are determined by the inaccuracies of the x-axis drive, which are in the form of a normal distribution with a standard deviation of 0.005mm. The control resolution (CR1) is determined by the pitch and encoder slots, while the accuracy is determined by 3σ, where σ is the standard deviation. The expected pulse frequency of the rotary encoder is necessary to measure and feedback the actual speed.

The pulse frequency is determined by dividing the linear velocity by the linear distance per pulse.

The system's x-axis motor speed in RPM, pulse frequency, control resolution (CR1), and accuracy axis along the x-axis are crucial parameters in an NC positioning system to ensure the required accuracy.
