Determine the intensity of shear of an oil having viscosity 0.1 Pa.s. The oil is used for lubricating the clearance between a shaft of diameter 10 cm and its journal bearing. The clearance is 1.5 mm, and the shaft rotates at 150 rpm.​

Answers

Note that the magnitude of the flux of momentum in the gap is 3.34 Pa and the momentum is being transported in the opposite direction of the shaft's motion.

What is the explanation for the above response?

To determine the intensity of shear of an oil with viscosity of 0.1 Pa.s, we can use the formula:

τ = μ × (2πN/60) × (r₁ - r₂) / h

Where:

τ = intensity of shear

μ = viscosity of oil = 0.1 Pa.s

N = rotational speed of shaft = 150 rpm

r₁ = radius of shaft = 10/2 = 5 cm

r₂ = radius of bearing = (10+0.15)/2 = 5.075 cm

h = clearance = 1.5 mm = 0.15 cm

Plugging in the values:

τ = 0.1 × (2π × 150/60) × (5 - 5.075) / 0.15

τ = -3.34 Pa

The negative sign indicates that the shear stress is in the opposite direction of the motion of the shaft. Therefore, the magnitude of the flux of momentum in the gap is 3.34 Pa and the momentum is being transported in the opposite direction of the shaft's motion.

A three-phase motor rated 25 hp, 480 V, operates with a power factor of 0.74 lagging and supplies the rated load. The motor efficiency is 96%. Calculate the motor input power, reactive power and current.

Answers

Answer:

the motor input power is 19.42 KW

the Reactive power is 17.65 KVAR

Current is 31.56 A

Explanation:

Given that;

V = 480V

h.p = 25 hp

p.f = 0.74 lagging

n_motor = 96%

so output = 25hp

and we know that;

1hp = 746 watt

watt = hp × 1hp

so output in watt = 25 × 746 = 18650 Watt = 18.65 KW

n_motor = (output / input) × 100

96 = 1865 / Input

96Input = 1865

Input = 1865 / 96

Input = 19.42 KW

Therefore the motor input power is 19.42 KW

P = √( 3 × V × I × cos∅)

19.42 = √( 3 ×480 × I × 0.74)

I = 31.56 A

Therefore Current is 31.56 A

Q = √( 3 × V × I × sin∅)

we know that

cos∅ = 0.74

so ∅ = cos⁻¹(0.74) = 42.26

so we substitute

Q = √( 3 × 480 × 31.56 × sin(42.26))

 = 17.65 KVAR

Therefore the Reactive power is 17.65 KVAR

Answers

In order to accomplish operations, the stack uses the LIFO (last in, first out) sequence or methodology. Two types of data structures, an array, and a linked list, can be used to build stacks in data structures.

Array: When a stack is used, an array is used to create it. Arrays are the working tool for every action. Pushing an item into the stack and popping an item out of the stack are the only two operations permitted in pushdown stacks. It is only possible to add and delete components from a stack from the top, making it a limited-access data structure. Adding anything to the stack's top with a push, taking something away with a pop, is known as pushing.

For a PTC with a rim angle of 80º, aperture of 5.2 m, and receiver diameter of 50 mm,
determine the concentration ratio and the length of the parabolic surface.

Answers

The concentration ratio for the PTC is approximately 1.48, and the length of the parabolic surface is approximately 5.2 meters.

To determine the concentration ratio and length of the parabolic surface for a Parabolic Trough Collector (PTC) with the given parameters, we can use the following formulas:

Concentration Ratio (CR) = Rim Angle / Aperture Angle

Length of Parabolic Surface (L) = Aperture^{2} / (16 * Focal Length)

First, let's calculate the concentration ratio:

Given:

Rim Angle (θ) = 80º

Aperture Angle (α) = 5.2 m

Concentration Ratio (CR) = 80º / 5.2 m

Converting the rim angle from degrees to radians:

θ_rad = 80º * (π / 180º)

CR = θ_rad / α

Next, let's calculate the length of the parabolic surface:

Given:

Aperture (A) = 5.2 m

Receiver Diameter (D) = 50 mm = 0.05 m

Focal Length (F) = A^{2} / (16 * D)

L = A^{2} / (16 * F)

Now we can substitute the given values into the formulas:

CR =\((80º * (π / 180º)) / 5.2 m\)

L = \((5.2 m)^2 / (16 * (5.2 m)^2 / (16 * 0.05 m))\)

Simplifying the equations:

CR ≈ 1.48

L ≈ 5.2 m

Therefore, the concentration ratio for the PTC is approximately 1.48, and the length of the parabolic surface is approximately 5.2 meters.

Using the same expression, calculate how many years it will take for the transistor count to increase by 100x

Answers

Answer:

No. of transistors = \($4.1524 \times 10^{10}$\) transistors

Explanation:

Given that:

N = \($1920 \times 10^{0.163(Y-1980)}$\)

Y = 2025

N = \($1920 \times 10^{0.163(2025-1980)}$\)

N = \($4.1524 \times 10^{10}$\) transistors

Now at Y = 1980

Number of transistors N = 1920

Therefore,

\($1000 = 10^{0.163(Y-1980)}$\)

\($\log_{10} 1000=0.163(Y-1980)$\)

\($\frac{3}{0.163}=Y-1980$\)

Determine the final temperature when air is expanded isentropically from 1425 kPa and 477°C to 100 kPa in a piston-cylinder device. Use the average specific heats from the ideal gas property tables. The final temperature is __ K.

Answers

The final temperature of air when expanded isentropically from 1425 kPa and 477°C to 100 kPa in a piston-cylinder device using the average specific heats from the ideal gas property tables is 315.5 K.

To determine the final temperature of air when expanded isentropically from 1425 kPa and 477°C to 100 kPa in a piston-cylinder device, we need to use the ideal gas law and the equation for isentropic expansion.
Firstly, we can use the ideal gas law to calculate the initial specific volume of air:
V1 = R*T1/P1
where V1 is the specific volume, R is the specific gas constant, T1 is the initial temperature (477°C = 750 K), and P1 is the initial pressure (1425 kPa).
V1 = 0.1989 m^3/kg
Next, we can use the equation for isentropic expansion to calculate the final specific volume of air:
V2 = V1*(P1/P2)^(1/gamma)
where V2 is the final specific volume, P2 is the final pressure (100 kPa), and gamma is the ratio of specific heats (1.4 for air).
V2 = 1.0265 m^3/kg
Finally, we can use the ideal gas law again to calculate the final temperature:
T2 = P2*V2/R
T2 = 315.5 K

An airline ticket counter forecasts that 220 people per hour will need to check in. It takes an average of 2 minutes to service a customer. Assume that arrivals are poisson distributed and service times exponentially distributed and that customers wait in a single queue for the first available agent.

a) If we want the average time a customer spends in the queue and in service to be 10 minutes or less, how many ticket agents should be on duty?
b) There airline wants to minimize the cost of idle ticket agents and the cost of customers waiting in the queue. The salary of a ticket agent is £12 per hour and the cost of a customer waiting in the queue is £5 per customer per hour. How many ticket agents should be on duty?​​

Answers

A) Number of agents required to achieve a wait time of 10 minutes or less = 8 agents

B) The number of agents required on duty to reduce cost = 9 agents

Given data :

Arrival rate of customers ( β ) = 220 per hour

Service rate ( mu ) = 60 minutes / 2 minutes = 30 customer per hour

utilization ( rho ) = 220 / 30 ≈ 7

at least 8 server personnel are required for stability of the queue

A) Determine the number of agents required to achieve a wait time of 10 minutes or less per customer

waiting time = 10 - 2 = 8 minutes

number of customers waiting ( ∝ ) = 7 and required server = 8

assuming   Lq = 5.2266

Hence the waiting time in line = Lq / arrival rate

                                                  = 5.2266 / 220 = 0.0238 hour

                                                  = 0.0238 * 60 = 1.428 minutes

Since the waiting time ( 1.428 minutes ) is less than the original waiting time ( 2 minutes ) the number of agents that will achieve a wait time of 10 minutes or less is = 8 agents

B) Determine the number of ticket agents that should be on duty to minimize cost

salary of ticket agent = £12 per hour

cost of customer waiting in queue = £5 per hour per customer

i) When 8 agents are used

waiting time of customers = 0.0238 * 220 = 5.236

waiting cost for customers = 5.236 * 5 = £26.18

employee cost = 8 * 12 = £96

∴ Total cost = 96 + 26.18

                    = £ 122.18

ii) When 9 agents are used

waiting time for customers = 0.0074 * 220 = 1.628

Wq = 1.6367 / 220 = 0.0074

waiting cost for customers = 1.6367 * 5 = £ 8.1835

assuming Lq = 1.6367

employee cost = 9 * 12 = £ 108

∴ Total cost = 108 + 8.1835 = £ 116.18

From the calculations in ( i ) and ( ii ) the Ideal number of ticket agents that should be on duty to minimize cost should be 9 agents.

Hence we can conclude that A) Number of agents required to achieve a wait time of 10 minutes or less = 8 agents and The number of agents required on duty to reduce cost = 9 agents.

given the standard cell potential for this cell is 0.115 v, and the measured cell potential is 0.0925, what is the concentration of chloride ions in the solution?

Answers

The concentration of chloride ions in the solution can be calculated by using the Nernst equation.

The Nernst equation is used to calculate the potential of an electrochemical cell under non-standard conditions. It relates the electrode potential to the concentrations of the species present in the solution.

The Nernst equation is:E = E° - (RT/nF) ln(Q)where, E is the cell potential under non-standard conditions,E° is the standard electrode potential, R is the gas constant, T is the temperature, n is the number of moles of electrons transferred, F is the Faraday constant, and Q is the reaction quotient.In this case, the standard cell potential (E°) is 0.115 V, and the measured cell potential (E) is 0.0925 V.

The reaction is given as:2AgCl(s) + 2e- → 2Ag(s) + 2Cl-(aq)We can see that n = 2 (two electrons are transferred in the reaction).The Nernst equation can be rearranged to solve for the concentration of chloride ions (Cl-) in the solution:ln(Cl-) = (E° - E)/(0.0592/n)ln(Cl-) = (0.115 - 0.0925)/(0.0592/2)ln(Cl-) = 0.378M[Cl-] = e^0.378M[Cl-] = 1.46 MTherefore, the concentration of chloride ions in the solution is 1.46 M.

for the following closed-loop system calculate the gains of compensator, kp and ki, such that a closed-loop response to a unit-step input has an overshoot (mp) of approx. 16% and a settling time (ts) of approximately 1 s (2%)

Answers

To calculate the gains of the compensator, Kp and Ki, in order to achieve a closed-loop response with approximately 16% overshoot (Mp) and a settling time of approximately 1 second (2%), we need to design a controller that meets these specifications.

1. Overshoot (Mp):

The overshoot of a closed-loop system is influenced by the damping ratio (ζ). The relation between overshoot and damping ratio is given by the equation: Mp = e^((-ζπ) / sqrt(1 - ζ^2)).

For a desired overshoot of 16% (0.16), we can solve the equation to find the damping ratio (ζ): ζ = sqrt((ln(Mp))^2 / (π^2 + (ln(Mp))^2)).

2. Settling Time (Ts):

The settling time is determined by the dominant closed-loop pole, which is related to the natural frequency (ωn) and damping ratio (ζ). The settling time is approximately 4 / (ζ * ωn).

For a settling time of 1 second (2%), we can solve the equation to find the natural frequency (ωn): ωn = 4 / (Ts * ζ).

Once we have obtained the values of ζ and ωn, we can design the compensator gains Kp and Ki based on the desired specifications.

It's important to note that the specific details of the closed-loop system or transfer function were not provided in the question, so further information would be needed to perform the calculations and determine the appropriate values of Kp and Ki.
