The conditions at states 1 and 2 are: Ti = 200 K, pi = 0.1 MPa and T2 = 300 K, p2 = 10 MPa. Level 0 represents the ideal gas limit, where the heat capacity is CP0 = 29.1 J/mole-K

The equation of state of the gas is given by the Van der Waals EOS, Eq (2.5):

p RT

pressure pi is calculated by substituting the EOS into the first equality of Eq (6.27) and integrating from p0 ~ 0 where CP = CP0 to p1; the common pressure of states 1 and A:
