The waste heat is released to a nearby lake. (i) Determine the power output and the rate of heat released. (ii) An inventor claimed that for the same amount of heat supplied, he will be able to design an improved heat engine delivering 145 MW of power, while operating between 30°C and 1170°C reservoirs. Investigate the validity of the claim. (b) Heat engine (B) receives 170 MW of heat from a furnace, and released 73 MW of heat to the atmospheric air. Due to some pressure drop in the pipelines, the heat engine lost an estimated 7 MW of heat to the surrounding. Determine the power output and thermal efficiency of the heat engine.arrow_forward
