a) A Canot heat engine receives heat from a reservoir at 700 C at a rate of 600 kJ/min and rejects the waste heat to the ambient air at 25°C. The entire work output of the heat engine is used to drive a refrigerator that removes heat from the refrigerated space at - 6°C and transfers it to the same ambient air at 25°C. Determine (a) the maximum rate of heat removal from the refrigerated space and (b) the total rate of heat rejection to the ambient air.

Question
a) A Carnot heat engine receives heat from a reservoir at 700°C at a rate of 600 kJ/min and
rejects the waste heat to the ambient air at 25°C. The entire work output of the heat engine is
used to drive a refrigerator that removes heat from the refrigerated space at - 6°C and
transfers it to the same ambient air at 25°C. Determine (a) the maximum rate of heat removal
from the refrigerated space and (b) the total rate of heat rejection to the ambient air.
