An air conditioner using R134a as the refrigerant has a compressor exit temperature of 1608F and an exit pressure of 200 psia. The refrigerant enters the compressor at 20 psia and 0 SF. The condenser cools the refrigerant to 1208F and 190 psia. For a cooling load of 15 Btu/s, determine:
(i) The mass flow rate
(ii) The isentropic efficiency of the compressor
(iii) The power input to the compressor
(iv) The rate of heat rejection by the condenser
(v) The coefficient of performance for this system
