drhodp – MUSST

private function drhodp(fl, p, t)

Function to calculate compressibility (drdp)T based on T and p

if fl is set to INC (incompressible) $\rho=0$
if fl is set to GP (perfect gas) $\rho=\frac{1}{r_g T}$ where $r_g$ is a member of fl FLUID
if fl is set to MIXT (mixture) $\rho=\frac{\lambda \rho_0^2 r_g T}{(p(1-\lambda) + \lambda r_g T \rho_0)^2}$ where $\lambda \' , \' \rho_0 \text{ and } r_g$ are members of fl FLUID
