12d Second law examples: Compressor and Nozzle

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 T-S diagram. THen…

10e Open system examples

Here I go through 2 examples of use of the SFEE for ideal gases. The fiart on is a turbine and the second one is an isothermal compressor. I show how to solve tese and what they mean.

10d Open Systems and the SFEE

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.

9b Four equations from one

Here I derive the four forms of the energy equation that we will use to solve different types of problem on this course. These are 1)For Closed Systems 2)For Steady Flow Thermal Systems 3)For…
