In a refrigeration cycle, the superheated R-134a (state 2) enters a compressor at 200oF and 90.0 psia. The R-134a (state 3) leaves the compressor at 360oF and 140 psia, and enters a condenser, where it is cooled by cooling water. The R-134a (state 4) leaves the condenser at 90.5oF and 120 psia as saturated liquid, and enters a throttling valve. The partially vaporized R-134a (state 1) leaves the valve at 100 psia. The cycle of R-134a is completed when it passes through an evaporator to absorb heat from the matter to be refrigerated. The flow rate of R-134a is 0.2 lb/s. The total power input is 91 Btu/s. The cooling water enters the condenser at 80oF and leaves at 115oF. The surroundings are at 210oF. Determine the efficiency in % of the compressor. please include necessary diagrams and formulas
