I'm struggling with a question on an assignment about thermodynamics:
Nitrogen gas, initially at a temperature of 170 K and a pressure of 100 bar, escapes from a thermally isolated tank with a volume of 0.15 m³ at a rate of 10 mol/minute. What will be the temperature and pressure in the tank after 50 minutes? Use the Peng-Robinson equation.
We have 2 MATLAB functions involving the PR equation at our disposal: one for finding the molar volume at a given temperature and pressure, one for finding the pressure at a given temperature and molar volume. I already have the molar volume at the beginning and the end of the process, and I figured that this can be considered an adiabatic expansion.
Any thoughts on how to solve this? I don't need a completely worked out answer, a correct and useful method would be just fine.
