As shown in the figure, Refrigerant 22 enters the compressor of an air conditioning unit operating at steady state at 40°F, 80 lb/in² and is compressed to 160°F, 200 lb/in². The refrigerant exiting the compressor enters a condenser where energy transfer to air as a separate stream occurs, and the refrigerant exits as a liquid at 200 lb/in2, 90°F. Air enters the condenser at 75°F, 14.7 lb/in² with a volumetric flow rate of 750 ft3/min and exits at 110°F. Neglect stray heat transfer and kinetic and potential energy effects, and assume ideal gas behavior for the air.

pls answer correctly the given
Exactly 10 kg of steam entered a heat exchanger at 100 bar and 560o C. At the exit the Steam was at 30 bar and a quality of 0.47. Please determine a. The exit temperature in oC. b. The mass of the liquid water in kg.
CHR 6. An inventor comes to you with a device that produces work. She tells you helium gas at 10 atm and 650 K enters the device and exits at 2 atm and 260 K. Assume an ideal gas with constant specific heat and the surroundings are at 25 C, Cp = 5.2 kJ/kg-K. Is this process possible assuming steady-state operation?
4.30 Refrigerant 134a enters a heat exchanger operating ai steady state as a superheated vapour at 10 bars. 60°C. where it is cooled and condensed to saturated liquid at 10 bars. The mass flow rate of the refrigerant is 10 kg/min. A separate stream of air enters the heat exchanger at 37°C with a mass flow rate of 80 kg/min. Ignoring heat transfer from the outside of the heat exchanger and neglecting kinetic and potential energy effects, determine the exit air temperature, in °C.
