Question: A heat engine takes 7 , 2 0 0 Joules as heat input and exhausts 2 , 4 0 0 Joules of heat to the

A heat engine takes 7,200 Joules as heat input and exhausts 2,400 Joules of
heat to the environment in one complete cycle.
a. How much work is done in one cycle?
b. What is the thermal efficiency of this engine?
c. If the operating temperatures are TH =1,500 C and TL =100 C, what is the Carnot
efficiency?
d. What is the exergy (second law or rational) efficiency of this engine? Exergy efficiency
is defined as the thermal efficiency against the max. (Carnot) efficiency
