Here I introduce an example of the Carnot cycle (open using air). I show that it forms a rectangle on the T-S diagram. I then show that this is the maximum efficiency of a heat engine cycle as: 1)…
Here I show that the area under the PV and TS diagrams are the work produced in a cycle. I show (again that the efficiency is the ratio between work out and heat in, but here I do it graphcally.
