Question 3: A heat engine is assumed to operate on a Carnot cycle. It receives 600kJ heat from a high temperature reservoir at 600°C and rejects heat to a low temperature reservoir at 20°C. ooooo Calculate the thermal efficiency of the cycle. What is QL? What is the net work produced by this cycle? Does this process violate Kelvin-Plank statement? Explain. An inventor claimed that he built a heat engine operating between the same reservoirs that give a thermal...
