13c The Carnot cycle

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)…

13b Power cycles and diagrams

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.

11c Efficiencies and the T-s diagram

Here I introduce the concept of efficiency. I show how these can be shown on a T-s diagram. THis gives the isentropic efficiency.

11c Second law processes and the T-s diagram

Here I introduce the T-s diagram for ideal gasses. I show that an isentropic expansion is a vertical upward line on this and an isentropic compression is a vertical downward line. I then show that in…
