This function calculates the time derivative of saturation temperature of R134a 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 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;
