11e Some more equations with entropyI take the first and second laws of thermodynamics and the gas laws to produce equations for the change in entropy for ideal gasses. I also show that an isentropic process is truly a polytropic one.

14b Example of Brayton cycleHere 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…

8b Ideal gas lawsHere I show the ideal gas laws. PV=mRT and P1V1/T1 = P2V2/T2. I also show how this can be applied to different gases using R=Ru/M

8a Liquids, gases, and steam diagramsHere I introduce liquids and gases. I go throught the processes whereby liquids turn to gases. I describe the regions on p-v and t-v diagrams.

10b Polytropic processesHere I show that the polytropic process is a good way of describing changes in condition for closed systems with ideal gasses. I look at different values of the exponent, n. Then I calculate some at…
