An ideal vapor compression refrigeration cycle operates at steady state with refrigerant 134a as the working fluid. saturated vapor enters the compressor at -14c, and saturated liquid leaves the condenser at 24c. the mass flow rate of refrigerant is 10 kg/min. determine: a) the compressor power; b) the refrigerant capacity; c) the coefficient of performance. ( h2 (kj/kg) = 269.52 via double interpolation).

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
