Heat engine of Carnot cycle gained heat at 850 K and dissipated
the heat to the outdoor at
330 K. The overall work output of the heat engine is used to drive
a Carnot refrigerator
that removes heat from the cooled space at (- 22) °C at a rate of
520 kJ/min and rejects it
to the same environment at 420 K. Determine:
(a) the rate of heat supplied to the heat engine.
(b) the total rate of heat rejection to the environment.
