Chapter 8, Problem 8.43P

A compressor receives R-410A as saturated vapor R-410A at 400 kPa and brings it to 2000 kPa, 60°C. Then a cooler brings it to saturated liquid at 2000 kPa (see Fig. below). Find the specific compressor work and the specific heat transfer in the cooler? A eccoi = Compressor Compressor section Cooler section

Please be very detailed

Solve it correctly and fast please.

A factory generates compressed air from 100 kPa, 17°C by compression to 800 kPa, 500 K, after which it cools in a constant pressure cooler to 300 K, (see Fig. P4.36). Find the specific compressor work and the specific heat transfer in the cooler. 1 2 3 Compressor -w. Compressor section Cooler section

Find COP of refrigerator and heat pump operating between temperatures 300 K and 900 K

A rigid insulated tank is separated into two rooms by a stiff plate. Room A of 0.5 m3 contains air at 250 Kpa, 300 K and room B is 1 m3 has air at 200 Kpa, 1000 K. the plate is removed and the air comes to a uniform state without any heat transferred. find the final temp and pressure of the room. An ideal gas is 45 psig and 800F is heated in a closed container to 130 0F. What is the final pressure? An air bubble rises from the bottom of a well where the temperature is 25 0C, to the surface where the temperature is 27 0C. Find the percent increase in the volume of the bubble if the depth of the well is 5m. Atmospheric pressure is 101.528 kPaa. A 3000 cm3 tank initially contains compressed air at 600 kPag and 28 oC. Determine the mass of air to be withdrawn from the tank to reduce its pressure to 80 kPag while the temperature remains unchanged.

9. Air is expanded from 400 kPa, 600 K in a polytropic process to 150 kPa, 400 K in a piston cylinder arrangement. Find the polytropic exponent n and the work and heat transfer per kg air using constant heat capacity.

Find the COP of refrigerator working between temperatures 350 K and 1050 K. What will be efficiency of heat engine operating in same temperature range?

Refrigerant R134a in piston cylinder assembly, 200 kPa in initial state pressure and in the form of saturated vapor. It is then reversed and The final pressure is 1000 kPa by being compressed in the adiabatic state change. a) Find the final temperature (°C). b) Find the work done (kj/kg). Note: The changes in kinetic and potential energies will be neglected.
