A heat engine operates between thermal reservoirs of 1200 K and 325 K. The engine produces 125 kW of work, and has a thermal efficiency of 47.4%.

(a) What is the rate of entropy change associated with the heat transfer into the engine?

$\displaystyle \frac{\text{kW}}{\text{K}}$

(b) What is the rate of entropy change associated with the heat transfer from the engine to the sink?

$\displaystyle \frac{\text{kW}}{\text{K}}$

(c) What is the total rate of entropy generation caused by this engine?

$\displaystyle \frac{\text{kW}}{\text{K}}$

(d) If this were a carnot heat engine instead, what would be the rate of entropy change associated with the heat transfer into the engine?

$\displaystyle \frac{\text{kW}}{\text{K}}$

(e) If this were a carnot heat engine, what would be the rate of entropy change associated with the heat transfer to the sink?

$\displaystyle \frac{\text{kW}}{\text{K}}$

(f) If this were a carnot heat engine, what would be the total entropy generation caused by its operation?

$\displaystyle \frac{\text{kW}}{\text{K}}$
