entropy_residual_pt Subroutine

private subroutine entropy_residual_pt(eos, n, P, T, root_type, Sr, SrP, SrT, Srn)

Calculate residual entropy given pressure and temperature.

Examples

eos = PengRobinson76(Tc, Pc, w)

n = [1.0_pr, 1.0_pr]
T = 300.0_pr
P = 1.0_pr

call eos%entropy_residual_pt(&
   n, P, T, root_type="stable", Sr=Sr, SrP=SrP, SrT=SrT, Srn=Srn &
   )
