Namespace: Altaxo.Science.Thermodynamics.FluidsAssembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3179.0 (4.8.3179.0)
Syntax public virtual double MassDensity_FromPressureAndTemperature(
double pressure,
double temperature,
double relativeAccuracy = 1E-06
)
Parameters
- pressure Double
- The pressure in Pa.
- temperature Double
- The temperature in Kelvin.
- relativeAccuracy Double (Optional)
- The target relative accuracy of the result.
Return Value
DoubleThe mass density in kg/m³
Remarks The density has to be calculated iteratively, using Newton-Raphson.
Therefore we need the target accuracy.
The iteration is ended if the pressure calculated back from the density compared with the pressure given in the argument
is within the relative accuracy.
