Reciprocal polynomial

Density, $\rho$ [kg/m$^3$]

$$\rho = \frac{1}{c_0 + c_1 T + c_2 T^2 + c_3 p + c_4 p T}$$

Entropy, $S$ [J/kg/K ]

$$S = 0$$

Compressibility, $\psi$ [s$^2$/m$^2$]

$$\psi = \left( \rho (c_3 + c_4 T) \right)^2$$

Usage

The rPolynomial equation of state is specified as:

equationOfState
{
    C       (<c0> <c1> <c2> <c3> <c4>)
}

Where

• C : Polynomial coefficients (x5)
