Question
Gas A and gas B (each at 25 °C and 20 bar) are perfectly mixed in an isothermal mixer at a constant pressure
of 20 bar as shown below where the molar flow rate of the outlet stream is 10 mol/s.
The following table provides partial entropy and specific entropy of each inlet streams relevant to the
operating conditions shown above:
partial S(J/mol.k) specific S(J/mol.k)
Gas A +30 +15
Gas B +50 +40
If the entropy change during this mixing process is 120 J/(K.s). Then, calculate:
a) Calculate the molar flow rate of stream A and stream B (in mol/s)
b) Does this gas mixing process follow the ideal-gas model? Justify with calculations.
