saturationTemperature_derp

Derivative of saturation temperature in two-phase region

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

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., ptriple ≤ p ≤ pcrit ).
