Plot the power produced and heat rejection rate to a cool reservoir for a cyclic heat engine that receives 100 kW of heat from a warm reservoir, for thermal efficiencies ranging from 0.05 to 0.70.
Given: Q?H = 100 kW
What will be an ideal response?
For a cycle: Wcycle = Qcycle
There are two heat transfers and one power, so Q?cycle=Q?H+Q?C=W?
From the thermal efficiency, W?=nQ?H
Then, Q?C=W??Q?H
For the given efficiency range:
Note, the absolute value of the heat rejection rate to the cool reservoir decreases as the thermal efficiency increases.
