A Carnot heat engine receives heat at 700 K and rejects the waste heat to the surroundings at 300 K. The output from the heat engine is used to drive a Carnot refrigerator that removes heat from the cooled space at -20 °C at a rate of 400 kJ/min and rejects it to the same surroundings at 300 K. Part B Determine the total rate of heat rejection to the surroundings. Express the heat transfer rate in kilojoules per minute to five significant figures. 15.

A Carnot heat engine receives heat at 700 K and rejects the waste heat to the surroundings at 300 K. The output from the heat engine is used to drive a Carnot refrigerator that removes heat from the cooled space at -20 °C at a rate of 400 kJ/min and rejects it to the same surroundings at 300 K. Part A Determine the rate of heat supplied to the heat engine. Express the heat transfer rate in kilojoules per minute to five significant figures. QH = 130.04 kJ/min Submit Previous Answers > Correct Correct answer is shown. Your answer 129.55 kJ/min was either rounded differently or used a different number of significant figures than required for this part.
