Unformatted text preview: reservoir. The heat engine is required to generate 3.7 kW. The mass flow rate of steam is 50 kg/hr. (a) What is the rate of heat removal (kJ/hr) from the steam? (b) Calculate the rate of heat rejection (kJ/hr) to the cold reservoir. (c) What is the thermal efficiency (%) of the heat engine? SP24: An internally reversible heat engine operates between 827 C and 17 C. The rate of heat rejection to the reservoir at 17 C is 100 kJ/min. One-half of the work output from the heat engine is used to drive an internally reversible heat pump. The heat pump operates between the reservoir at 17 C and a home maintained at 37 C. (a) Determine the net power delivered (kW) by the heat engine. (b) What is the rate of heat transfer (kJ/min) delivered to the home? (c) Calculate the net rate of heat transfer (kJ/min) for the reservoir at 17 C....
