Detailed Description

The density of an exponentially compressible fluid.

[in]psiThe pressure head (not used)
[in]rwork[0]The reference density, \( \rho_0 \)
[in]rwork[1]The reference pressure head, \( \psi_0 \)
[in]rwork[2]The compressibility \( \beta \)
[out]rhoThe density
[out]drhoThe derivative of density with respect to pressure head

This is a trivial function but it demonstrates the density relation interface.

\[ \rho &= \rho_0 e^{\beta_f \psi} \]
