"A two-evaporator compression refrigeration system uses R-134a as the working fluid. The system operates evaporator 1 at 0 C, evaporator 2 at -26.4C, and the condenser at 800 kPa. The refrigerant is circulated through the compressor at a rate of 0.1 kg/s and the low temperature evaporator serves a cooling load of 8 kW.

Determine:
(a) The cooling rate of the high-temp evaporator
(b) The power required by the compressor
(c) The coefficient of performance
(d) Draw a T-s diagram of this cycle"
