The Second Law: Heat Engines, the Carnot Cycle and Efficiency

Control console

Record pressure against volume through one complete revolution and find the area of the loop.

Hot end temperature

Cold end temperature

pwrmeasfault

Set the hot and cold end temperatures and take a diagram.
Integrate the loop numerically to obtain the work per cycle. Check the sign convention: a clockwise loop delivers work.
Repeat at three hot-end temperatures and comment on how the area changes.
Compare the loop with the ideal Stirling cycle of two isotherms and two isochores, and explain the differences.
