a carnot heat engine uses water as the working fluid. the water changes from saturated liquid to saturated vapor at 200C as heat is added. heat is rejected in a constant pressure process at 20 kPa. to work from this heat engine is used to power a carnot cycle refrigerator that operates between -15C and +20C. However, due to losses between the heat engine and the refrigerator, only 87.3% of the turbine work from the heat engine is available to the compressor of the refrigerator . The flow rate of the water in the heat engine is 0.01 kg/sec.fo this system determine the following. A) the efficiency of the heat engine, B) the heat added to the water in the heat engine, C)the work done by the heat engine, and D)the number of tons of refrigeration provided by the refrigerator
