High-temperature reservoir at Ty= 652°C Qu=500 kJ 5.2.1 A Carnot heat engine receives 500 kJ of heat per cycle from a high-temperature source at 652°C and rejects heat to a low-temperature sink at 30°C. Determine Was Camot НЕ 135,000 kJ/h Heat loss (a) the thermal efficiency of this Carnot engine; (Ъ) the rejected to the sink per cycle. House Low-temperature reservoir at T = 30°C amount of heat Ty =21°C 5.2.2 A heat pump is to be used to heat a house during the winter. The house is to be maintained at 21°C at all times. The house is netin estimated to be losing heat at a rate of 135,000 kJ/h when the outside temperature drops to - 5°C. Determine the minimum power required to drive this heat pump.
