Detailed Description

The density of a linearly compressible fluid.

Parameters

[in]	psi	The 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]	rho	The density
[out]	drho	The derivative of density with respect to pressure head

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

\[ \rho &= \rho_0 [1+\beta(\psi - \psi_0) ] \]
