TS diagram vs Bietie-Bridgemann Equation
TS diagram vs Bietie-Bridgemann Equation
(OP)
Hello,
I am trying to calculate an isothermal change of Nitrogen gas from 1000 cc at 100 bar compressing to 200 cc and I am looking for a final pressure of the gas.
Two methods were recommended by two different people. One was to use TS diagram and the other was to use one of the real gas equations, Bietie-Bridgemann Equation. Which one calculate closer to a real result and why? Why are they different?
Thanks in advance.

Another question.... I've got TS diaram for Nitrogen prepared by F.DIN 1958 which is big and there are so many lines of pressures, entalpy and volumes. Do you mean that they are all empirical?
