The thermal energy reservoirs of an ideal gas carnot cycle are at 1240°f and 40°f, and the device executing this cycle rejects 70 btu of heat each time the cycle is executed. determine the total heat supplied to and the total work produced by this cycle each time it is executed. the total heat supplied to the cycle isbtu/cycle the total work produced by this cycle isbtu/cycle.

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
