A Carnot heat engine receives heat at 850 K and
rejects the waste heat to the environment at 298 K.
The entire work output of the heat engine is used to drive a Carnot
refrigerator that removes heat
from the cooled space at -17⁰C at a rate of 450 kJ/min and rejects
it to the same environment at 298
K. Determine;
(a) the rate of heat supplied to the heat engine and
(b) the total rate of heat rejection to the environment.
Here we use Carnot Theorem to solve this problem. A detailed analysis has been given below in the pictures
