WebAnswered: The thermal effiency of a general heat… bartleby. ASK AN EXPERT. Engineering Mechanical Engineering The thermal effiency of a general heat engine is 35 percent, and it produces 60 hp. At what rate is heat transferred to this engine, in kJ/s. The thermal effiency of a general heat engine is 35 percent, and it produces 60 hp. WebThe rate at which heat moves depends on the driving force ∆T and the resistance. The area (A) and overall heat transfer coefficient (U) can be combined to represent the resistance to heat flow (UA). The greater the driving force the faster heat moves into the refrigerator. The greater the resistance the slower heat moves. The amount of heat ... WebThe engine drives a reversible refrigerator which operates between reservoirs at temperatures of 50°C and – 25°C. The heat transfer to the engine is 2500 kJ and the net work output of the combined engine refrigerator plant is 400 kJ.
