Question 2 20 pts A Carnot heat engine receives heat at 530 C and rejects the waste heat at 70 C. Eight five percent of work output from the heat engine is used to power a Carnot refrigerator that removes heat from the -20 C cold space at a rate of 500 kJ/min and rejects heat to the same reservoir as the heat engine, at 70 C. Determine the rate at which heat supplied to the heat engine, and the total rate of heat rejected to the 70 C environment.
