Aheat puinp that operatcs on the ideal vapor-compression cycle with refrigeran 134a is used to heat a house. the nass flow ratc of the re rigeranl is 0.5 kgs. the condenser and ev aporator pressures are 900 ard 200 kpa, respectively (a)show the cycle on a 7.s diagram with respect suluration lines, and dicternine: (b)the raic of heut supply to the house (c) the volume tlow rate of the refrigerant at thc compressor inlet; (d)the cop of this hcal pump.

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
