A Carnot heat engine receives heat at 900 K and rejects the waste heat to the environment at 300 K. The entire work output of the heat engine is used to drive a Carnot refrigerator that removes heat from the cooled space at -15°C at a rate of 250 kJ/min and rejects it to the same environment at 300 K. Determine (a) the rate of heat supplied to the heat engine and (b) the total rate of heat rejection to the environment.

Question
A Carnot heat engine receives heat at 900 K and rejects
the waste heat to the environment at 300 K. The entire work
output of the heat engine is used to drive a Carnot refrigerator
that removes heat from the cooled space at -15°C at a rate of
250 kJ/min and rejects it to the same environment at 300 K.
Determine (a) the rate of heat supplied to the heat engine and
(b) the total rate of heat rejection to the environment.
