Here I go through an example of a Brayton cycle. I show that, using previous knowledge of devices, we can calculte the heat and work terms for the three devices and therefore work out the efficiency…

Here I work through two examples of the effect of isentropic efficiency on devices. I use the nozzle and the compressor as examples. I show that you need to produce a system and a TS diagram. THen…

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

Here I introduce the Ts 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…

Here I derive the steady flow energy equation for thermal systems. I show how it can be used for calculating the work in an adiabatic process using the gas laws.
