Unformatted text preview: at 200 kPa and leaving as saturated vapor. The heat is supplied by a Carnot heat pump operating from a low-temperature reservoir at 16C. Find the rate of work into the heat pump. 5. A refrigerator keeping 5C inside is located in a 30C room. It must have a high temperature T above room temperature and a low temperature T below the refrigerated space in the cycle to actually transfer the heat. For a T of 0, 5 and 10C respectively calculate the COP assuming a Carnot cycle. 6. An ideal gas Carnot cycle with air in a piston cylinder has a high temperature of 1200 K and a heat rejection at 400 K. During the heat addition the volume triples. Find the two specific heat transfers (q) in the cycle and the overall cycle efficiency....
