14. Introduction to heat cycles

Question 1

How can we work out net heat or net work using pv/Ts diagrams for a process (same start and end points)?

Answer 1

Note: Internal energy must be zero, so the Qnet = Wnet so both ts and pv diagram show the same thing.

Question 2

What is a simple pv diagram for a heat engine and pump?

Answer 2

Question 3

What are the basic efficiency equations for a heat engine?

Answer 3

Question 4

what are the three ways to maximise efficiency of an engine?

Answer 4
