Question

I need the answer as soon as possible

Example (Q1): A turbo-compressor takes 969 ft/min
volume of refrigerant gas for the operation of the air-
conditioning unit, at atmospheric pressure of 14.7 psi and
temperature of 520°R, and compresses the gas to pressure
24.7psi. figure Q1, Calculate,
(i) The delivery temperature.
(ii) The horse-power (HP) required in kilo-watts (kw).
Given data: Adiabatic isentropic-index for the gas
refrigerant is Y= 1.25, and the mixture heat capacity CP =
0.539, J = 778, the density of the refrigerant gas at the
given pressure and temperature is =1 Ib/ft3.
One horse power (HP) = 746 watts

Just (b) and (c) please!
can you solve part B without just using those tables to find the answer?
An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
There may or may not be one or more mistakes in the solution. Go through the solution carefully and then do the following. 1. State if the solution is correct or incorrect 2. If the solution is incorrect, identify what is the mistake in the solution. Be specific and succinct. 3. If the solution is incorrect, provide the final solution with appropriate steps. Problem: A refrigeration cycle uses refrigerant R-134a to cool down water from 40°C to 20°C. The refrigerant R-134a enters the cycle as saturated liquid at -15°C and exits as saturated vapor at the same temperature. The mass flow rate of R-134a is 0.12 kg/s. The overall heat transfer coefficient is 1400 W/m².K. The surface area of the heat exchanger is 1.4 m². What is the rate at which heat is being exchanged between R-134a and water? Assume that the heat exchanger is perfectly insulated from outside (i.e., there is no convection or radiation with the outside/surrounding). Solution: We know, from the definition of overall heat…
When does force work?
hints: The ﬂask will be filled with water (at a constant rate of 500 gallons per minute). It will take me exactly 10 minutes to escape from the chains. The diameter of the tank at 1 foot intervals. I am 5 feet 9 inches tall, and I'm pretty skinny so that you can ignore both my volume and the volume of the stool in your analysis. A gallon is equal to 0.13368 cubic feet. You can think of the volume and the height of the water as functions of time. You can easily find an expression for V (t), and then use your expression for volume in terms of height to solve for h(t). after 10 minutes amount of water in the tank=66.84 ft3 t=69.3 minutes h(t)=e66.84t/100? -1 h(10)=e66.84(10)/100? -1=7.39 ft Height of stool=1.64 ft Height of water in the tank=7.39 ft Questions: show work How fast is the water rising?

What’s the correct answer please?
The solution (298.349) is incorrect as well.
13. The amount of heat (Hth, thermal energy) stored in rocks, m = 500 kg, S = 840 J/(kg °C), Tfinal =50°C, Tinitial = 40°C is: ·Hth = 19*10E(6) Joules. ·Hth = 4.2 * 10E(6) Joules. %3D ·Hth = 4.2*10E(4)Joules. %3D
