Unformatted text preview: in the cycle. (d) What is the heat transfer (kJ) and work (kJ) for this cycle? SP9: A heat pump has coefficient of performance of 3. The rate of heat transfer from the heat pump cycle is 300 kW. The heat pump cycle is operated by a power cycle. The rate of heat transfer into the power cycle is 250 kW. (a) What is the thermal efficiency (%) of the power cycle? (b) Determine the amount of heat (kW) received by the heat pump cycle. SP10: A 0.5 m 3 rigid vessel initially contains a saturated liquid-vapor mixture of water at 100 C. The water is heated until it reaches its critical point. (a) Indicate the process on a P-v diagram, (b) What is the mass of liquid water (kg) at the initial state? (c) Determine the volume occupied by vapor (m 3 ) at the initial state....
