Air at 290 K, 100 kPa enters a compressor operating at steady state and is compressed adiabatically to an exit state of 420 K, 330 kPa. The air is modeled as an ideal gas, and kinetic and potential energy effects are negligible. For the compressor:
a. Determine the rate of entropy production, in kJ/K per kg of air flowing
b. The isentropic compressor efficiency.
a)The rate of entropy production: ΔSgen = s₂-s₁ΔSgen = 2.01699 - 1.66802ΔSgen = 0,349kj/Kg-K.
Air enters the compressor at steady state, means no change in properties with respect to time. We'll use ideal gas properties of air to find the entropy at the initial and final state. The isentropic efficiency of the compressor is given by the following formula:
ηₐ = h₁ -h₂ₓ ÷ h₁ -h₂
Where,
h is the specific enthalpy at respective state.
We're given the following information in the problem:
T₁ = 290 KP₁ = 100 kPaP₂ = 330 kPaT₂ =
We'll draw the T-S diagram of the process as shown below:
Using the ideal gas properties of air:
Specific entropy at entry state, S₁ = 1.66802 kJ/Kg -K
Specific entropy at exit state, S₂=2.01699 kJ/Kg - K.
(a) The rate of entropy production: ΔSgen = s₂-s₁ΔSgen = 2.01699 - 1.66802ΔSgen = 0,349kj/Kg-K.
(b) The isentropic compressor efficiency.
Using the ideal gas properties of air: Relative pressure at the state 2s (shown in the diagram): Pr₂ = Pr₁ ₓ -Pr₂/Pr₁ = 1.2311 ˣ 330/100 = Pr₂ = 4.0626
Using the ideal gas properties of air at Pr= 4.0626
h₂ₙ = 408.5 kJ/Kg-K.
Also, specific enthalpy at the entry and exit are:
h₁ = 290.16 kJ/Kg - Kh₂ = 421.26 kJ/Kg
The isentropic compressor efficiency:
ηₐ = h₁ -h₂ₓ ÷ h₁ -h₂
ηₐ = 290.16 - 408.5 /290.16 - 290.16 -421.26ηₐ = 0.9

8. 15 A manual arc welding cell uses a welder and a fitter. The cell operates 2,000 hriyr. The welder is paid $30/hr and the fitter is paid $25/hr. Both rates include applicable overheads. The cycle time to complete one welded assembly is 15. 4 min. Of this time, the arc-on time is 25%, and the fitter's participation in the cycle is 30% of the cycle time. A robotic arc welding cell is being considered to replace this manual cell. The new cell would have one robot, one fitter, and two workstations, so that while the robot is working at the first sta tion, the fitter is unloading the other station and loading it with new components. The fitter's rate would remain at $25/hr. For the new cell, the production rate would be eight welded assemblies per hour. The arc-on time would increase to almost 52%, and the fitter's participation in the cycle would be about 62%. The installed cost of the robot and worksta tions is $158,000. Power and other utilities to operate the robot and arc welding equipment will be $3. 80/hr, and annual maintenance costs are $3,500. Given a 3-year service life, 15% rate of return, and no salvage value, (a) determine the annual quantity of welded assem blies that would have to be produced to reach the break-even point for the two methods. (b) What is the annual quantity of welded assemblies produced by the two methods work. Ing 2,000 hryr?
The annual quantity of welded assemblies that would have to be produced to reach the break-even point for the two methods is approximately 15,983.
To determine the break-even point between the manual arc welding cell and the robotic cell, we need to calculate the total costs for each method and then equate them.
For the manual arc welding cell:
Labor cost per hour = (welder's hourly rate x arc-on time) + (fitter's hourly rate x fitter's participation in the cycle) = ($30 x 0.25) + ($25 x 0.3) = $11.25
Labor cost per welded assembly = labor cost per hour x cycle time per assembly / 60 = $11.25 x 15.4 / 60 = $2.89
Overhead cost per welded assembly = (labor cost per hour x (1 - arc-on time - fitter's participation in the cycle)) x cycle time per assembly / 60 = ($30 x 0.45) x 15.4 / 60 = $4.68
Total cost per welded assembly = labor cost per welded assembly + overhead cost per welded assembly = $2.89 + $4.68 = $7.57
Total cost per hour = total cost per welded assembly x production rate = $7.57 x 8 = $60.56
Total cost per year = total cost per hour x hours of operation per year = $60.56 x 2,000 = $121,120
For the robotic arc welding cell:
Labor cost per hour = fitter's hourly rate x fitter's participation in the cycle = $25 x 0.62 = $15.50
Labor cost per welded assembly = labor cost per hour x cycle time per assembly / 60 = $15.50 x 15.4 / 60 = $3.97
Overhead cost per welded assembly = power and utility cost per hour + annual maintenance cost / production rate = $3.80 + $3,500 / (8 x 2,000) = $3.80 + $0.22 = $4.02
Total cost per welded assembly = labor cost per welded assembly + overhead cost per welded assembly + (installed cost / (production rate x service life)) = $3.97 + $4.02 + ($158,000 / (8 x 3)) = $3.97 + $4.02 + $6,208.33 = $14.19
Total cost per hour = total cost per welded assembly x production rate = $14.19 x 8 = $113.52
Total cost per year = total cost per hour x hours of operation per year = $113.52 x 2,000 = $227,040
To find the break-even point, we set the total cost of the manual arc welding cell equal to the total cost of the robotic arc welding cell and solve for the annual quantity of welded assemblies:
$121,120 + x($7.57) = $227,040 + x($14.19)
$7.57x - $14.19x = $227,040 - $121,120
$-6.62x = $105,920
x = $105,920 / $6.62
x = 15,982.7
Therefore, the annual quantity of welded assemblies that would have to be produced to reach the break-even point for the two methods is approximately 15,983.

Solution: x² + 200x = 166400 => x(x + 200) = 166400 166400 = 320 * 520 => (320)(320 + 200) = 166400 => x = 320 side length of the current square park. = 320 m Learn More: Which expression is a possible leading term for the polynomial ... brainly.In/question/13233517
Answer:
320 m
Explanation:
To find the side length of the current park, x, we solve the quadratic equation for the area of the park
x² + 200x = 166400
x² + 200x - 166400 = 0
We multiply -166400 by x² to get -166400x². We now find the factors of 166400x² that will add up to 200x. These factors are -320x and 520x
So, we re-write the expression as
x² + 200x - 166400 = 0
x² + 520x - 320x - 166400 = 0
We write out the factors of the expression,
x² + 520x - 320x - 320 × 520 = 0
Factorizing the expression, we have
x(x + 520) - 320(x + 520) = 0
(x + 520)(x - 320) = 0
x + 520 = 0 or x - 320 = 0
x = -520 or x = 320
Since x is not negative, we take the positive answer.
So, x = 320 m
15 kg of ice at 0°C is heated to water of temperature 20°C. What is the amount of heat required if the specific latent heat of ice fusion is 335 kJ/kg and the specific heat capacity of water is 4.19kJ/kg/°C?
Answer:
6282 kJ
Explanation:
Given that:
The mass (m) = 15 kg
The specific latent heat of ice fusion \(h_{fg}_{ice}\) = 335 kJ/kg
The specific heat capacity of water = 4.19 kJ/kg.c
The initial temperature of the ice \(T_i\)= 0° C
The final temperature of the water \(T_f\) = 20° C
To find the needed amount of heat to convert 0° C ice to 20° C of water.
To do that, we need to find the latent heat required for the phase change from 0° C ice to 0° C water, then the heat required to convert 0° C water to 20° C water.
Heat required = \(m \times h_{fg}_{ice}+ m \times c_{water} \times \Delta T\)
Heat required = (15 × 335) + (15 × 4.19) × (20 - 0)
Heat required = 5025 + 62.85 × 20
Heat required = 5025 + 1257
Heat required = 6282 kJ
A square aluminum plate 5 mm thick and 150 mm on a side is heated while vertically suspended in quiescent air at 75°c. determine the average heat transfer coefficient for the plate when its temperature is 15°c by two methods: using results from the similarity solution to the boundary layer equations, and using results from an empirical correlation.
By using the boundary layer equation, the average heat transfer coefficient for the plate is equal to 4.87 W/m²k.
Given the following data:
Surface temperature = 15°C
Bulk temperature = 75°C
Side length of plate = 150 mm to m = 0.15 meter.
How to calculate the average heat transfer coefficient.Since we have a quiescent room air and a uniform pole surface temperature, the film temperature is given by:
\(T_f=\frac{T_{s} + T_{\infty} }{2} \\\\T_f=\frac{15 + 75 }{2} \\\\T_f = 45\)
Film temperature = 45°C to K = 273 + 45 = 318 K.
For the coefficient of thermal expansion, we have:
\(\beta =\frac{1}{T_f} \\\\\beta =\frac{1}{318}\)
From table A-9, the properties of air at a pressure of 1 atm and temperature of 45°C are:
Kinematic viscosity, v = \(1.750 \times 10^{-5}\) m²/s.Thermal conductivity, k = 0.02699 W/mk.Thermal diffusivity, α = \(2.416 \times 10^{-5}\) m²/s.Prandtl number, Pr = 0.7241.Next, we would solve for the Rayleigh number to enable us determine the heat transfer coefficient by using the boundary layer equations:
\(R_{aL}=\frac{g\beta \Delta T l^3}{v\alpha } \\\\R_{aL}=\frac{9.8 \;\times \;\frac{1}{318} \;\times \;(75-15) \;\times \;0.15^3 }{1.750 \times 10^{-5}\; \times \;2.416 \times 10^{-5} } \\\\R_{aL}=\frac{9.8\; \times 0.00315 \;\times \;60\; \times\; 0.003375 }{4.228 \times 10^{-10} }\\\\R_{aL}=1.48 \times 10^{7}\)
Also take note, g(Pr) is given by this equation:
\(g(P_r)=\frac{0.75P_r}{[0.609 \;+\;1.221\sqrt{P_r}\; +\;1.238P_r]^\frac{1}{4} } \\\\g(P_r)=\frac{0.75(0.7241)}{[0.609 \;+\;1.221\sqrt{0.7241}\; +\;1.238(0.7241)]^\frac{1}{4} }\\\\g(P_r)=\frac{0.543075}{[0.609 \;+\;1.221\sqrt{0.7241}\; +\;1.238(0.7241)]^\frac{1}{4} }\\\\g(P_r)=\frac{0.543075}{[2.5444]^\frac{1}{4} }\\\\g(P_r)=\frac{0.543075}{1.2630 }\)
g(Pr) = 0.430
For GrL, we have:
\(G_{rL}=\frac{R_{aL}}{P_r} \\\\G_{rL}=\frac{1.48 \times 10^7}{0.7241} \\\\G_{rL}=1.99 \times 10^7\)
Since the Rayleigh number is less than 10⁹, the flow is laminar and the condition is given by:
\(N_{uL}=\frac{h_{L}L}{k} = \frac{4}{3} (\frac{G_{rL}}{4} )^\frac{1}{4} g(P_r)\\\\h_{L}=\frac{0.02699}{0.15} \times [\frac{4}{3} \times (\frac{1.99 \times 10^7}{4} )^\frac{1}{4} ]\times 0.430\\\\h_{L}= 0.1799 \times 62.9705 \times 0.430\\\\h_{L}=4.87\;W/m^2k\)
Based on empirical correlation method, the average heat transfer coefficient for the plate is given by this equation:
\(N_{uL}=\frac{h_{L}L}{k} =0.68 + \frac{0.670 R_{aL}^\frac{1}{4}}{[1+(\frac{0.492}{P_r})^\frac{9}{16}]^\frac{4}{19} } \\\\h_{L}=\frac{0.02699}{0.15} \times ( 0.68 + \frac{0.670 (1.48 \times 10^7)^\frac{1}{4}}{[1+(\frac{0.492}{0.7241})^\frac{9}{16}]^\frac{4}{19} })\\\\h_{L}=4.87\;W/m^2k\)

The ASIAN Transmission company makes and sells certain automotive parts present sales volume is 500,000 units per year at selling price of fifty centavos (₱0.50) per unit. Fixed expenses total ₱80, 000 per year.
5. What is the present total profit for a year?
6. What is the breakeven units of productions?
Answer:
5. ₱170,000
6. 160,000 units
Explanation:
5. At a sales volume of 500,000 units, the revenue is ...
₱0.50 × 500,000 = ₱250,000
The profit s the difference between revenue and cost:
profit = ₱250,000 -₱80,000
profit = ₱170,000
__
6. The break-even quantity is the number that produces a revenue equal to cost:
₱0.50×q = ₱80,000
q = ₱80,000/₱0.50 = 160,000
The break-even quantity is 160,000 units.

What major financial flop led to the end of the Sega Dreamcast and ultimately caused Sega to stop making game consoles altogether?
1: The founder and CEO of Sega was found to be secretly skimming money off of the top of profits, leading to widespread distrust by the public and a sharp decline in sales until they ultimately had to shut down due to making no profit.
2: A small group of employees found a way to drain all of the Sega Corporation funding accounts and flee the country with all of the money, never to be heard from again.
3: A game called Shenmue, that cost more than $70 million to make, meant that everyone who owned a Dreamcast needed to buy two copies of the game just for Sega to make back the money they had spent to develop it-which didn't happen.
4: A game called Katamari Damacy that carried a virus that would infect any console that it was played on forced Sega to spend millions of dollars in refunds and bankrupted the company.

Create an abstract class DiscountPolicy. It should have a single abstract method computeDiscount that will return the discount for the purchase of a given number of a single item. The method has two parameters, count and itemCost. 2. Derive a class BulkDiscount from DiscountPolicy, as described in the previous exercise. It should have a constructor that has two parameters, minimum and percent. It should define the method computeDiscount so that if the quantity purchased of an item is more than minimum, the discount is percent percent. 3. Derive a class BuyNItemsGetOneFree from DiscountPolicy, as described in Exercise 1. The class should have a constructor that has a single parameter n. In addition, the class should define the method computeDiscount so that every nth item is free. For example, the following table gives the discount for the purchase of various counts of an item that costs $10, when n is 3: count 1 2 3 4 5 6 7 Discount 0 0 10 10 10 20 20
4. Derive a class CombinedDiscount from DiscountPolicy, as described in Exercise 1. It should have a constructor that has two parameters of type DiscountPolicy. It should define the method computeDiscount to return the maximum value returned by computeDiscount for each of its two private discount policies. The two discount policies are described in Exercises 2 and 3. 5. Define DiscountPolicy as an interface instead of the abstract class described in Exercise 1.

explain how the addition of a second winding to a single-phase induction motor allows them to produce a torque under starting conditions?
When a single-phase induction motor has a second winding, it allows it to produce torque under starting conditions. The addition of a second winding to a single-phase induction motor makes it possible to produce a rotating magnetic field that is approximately equal to that produced by a three-phase motor.
This rotating magnetic field is used to create torque in the rotor. The two windings on the stator have different numbers of turns and are typically wound with different wire diameters to provide the necessary phase shift. The primary winding, which is usually on the outer circumference of the stator, is wound with a thicker wire and has a larger number of turns. The secondary winding, which is typically placed inside the primary winding, is wound with a thinner wire and has fewer turns.
To create a rotating magnetic field with a single-phase supply, the secondary winding is given a phase shift relative to the primary winding. When the primary winding is energized, it creates a magnetic field that is nearly stationary. When the secondary winding is energized, it creates a magnetic field that is displaced in space and time from the primary field. The combined fields create a rotating magnetic field that rotates at a rate determined by the frequency of the supply.
The rotor of the induction motor is then attracted to this rotating magnetic field and begins to rotate. The torque produced by the motor depends on the strength of the magnetic field and the amount of slip between the rotor and the rotating field. The slip is the difference in speed between the rotating field and the rotor, and it is what allows the rotor to accelerate and produce torque.
