Problem 14DQ

Real heat engines, like the gasoline engine in a car, always have some friction between their moving parts, although lubricants keep the friction to a minimum. Would a heat engine with completely frictionless parts be 100% efficient? Why or why not? Does the answer depend on whether or not the engine runs on the Carnot cycle? Again, why or why not?

Step-by-Step Solution:

Solution 14DQ Step 1: The definition of thermal efficiency of heat engine is e = W/ Q| | | H | e = 1 Q / Q | | | C| | H | In order for e = 1,one would need thermal energy U contained in the exchange to be U = Q =C0.
