The hot shot thermodynamic engine operating between 40C and 380C has an efficiency that is 60 of that of an ideal Carnot engine operating between the same temperatures.

If the hot shot engine absorbs energy at a rate of 60 kW, at what rate does it exhaust energy? A) 36 kW
B) 41 kW
C) 57 kW
D) 60 kW

A) 27
B) 0.27
C) 100
D) 1.0
