Saturation pressure of water above the triple point temperature is computed from temperature.

Source: A Saul, W Wagner: "International equations for the saturation properties of ordinary water substance", equation 2.1

psat_der = saturationPressureLiquid_der(Tsat, dTsat)

Tsat	Type: Temperature (K) Description: Saturation temperature
dTsat	Type: Real (K/s) Description: Saturation temperature derivative

psat_der	Type: Real (Pa/s) Description: Saturation pressure derivative
