This function calculates the derivative of saturation temperature of R134a with regard to the state variable p (absolute pressure). The non-derivative function is saturatuionTemperature.

Restrictions

It is only valid in the two-phase region (i.e., p_triple ≤ p ≤ p_crit ).

dTp = saturationTemperature_derp(p)

p	Type: AbsolutePressure (Pa) Description: Pressure

dTp	Type: DerTemperatureByPressure (K/Pa) Description: Derivative of saturation temperature w.r.t. pressure
