      du = cv*dT + (T*((dp/dT)_v)-p)* dv u is the internal energy cv is calculated from cp which is input by the user, the a0->a5 coefficients. This is just a polynomial so the analytic integral is exact. dp/dT is analytically evaluated from the EOS Once the internal energy is calculated, enthaply can be calculated using h = u+ p*v
