The course text is probably the clearest layout for students of thermodynamics. I am now in graduate school, and I am referring to them regularly. Your students are very luck to have you! Thank you for sharing your lectures and notes!

Nice approach. It is formally correct however, rather than dividing Tds+Vdp by dp and then switching the d's to dels, to express the fundamental equations in terms of finite differences - i.e., with Deltas rather than differentials. That way, you can divide by Delta-P and take the limit as Delta-P tends to zero to get the required partial derivative.

Great video but, what if the gas can not be considered ideal because of high pressure and high temperature conditions? Which equation of state do you suggest to implement in that case?
@AndrewPaluch
@AndrewPaluch Жыл бұрын
Great question! Actually, for a real fluid the approach would be to compute the change in enthalpy as the sum of the change in the residual enthalpy and the ideal gas enthalpy. The change in the ideal gas enthalpy may readily be computed so long as the ideal gas heat capacity is known. The residual term would be computed using an equation of state. In the course, we typically use the SRK equation of state for illustrative purposes, and you can find some examples where we computed this using MATLAB. But the choice of SRK is just illustrative, in that if you can perform the calculations with SRK, you could perform the calculations with others.

Since it's a function of temperature and pressure, do we assume constant Volume?
