This function calculates the time derivative of saturation temperature of R245fa with regard to the time derivative of p. The non-derivative function is saturatuionTemperature.
It is only valid in the two-phase region (i.e., ptriple ≤ p ≤ pcrit ).
function saturationTemperature_der_p extends Modelica.Icons.Function; input Modelica.Units.SI.AbsolutePressure p "pressure"; input Real der_p "time derivative of pressure"; output Real der_Tsat "time derivative of saturation temperature"; end saturationTemperature_der_p;
