HelmholtzEquationOfStateMassDensity_FromPressureAndTemperature(DimensionfulQuantity, DimensionfulQuantity, Double) Method

Gets the mass density for a given pressure and temperature.

Namespace: Altaxo.Science.Thermodynamics.Fluids
Assembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3448.0 (4.8.3448.0)
Syntax

Copy
public DimensionfulQuantity MassDensity_FromPressureAndTemperature(
	DimensionfulQuantity pressure,
	DimensionfulQuantity temperature,
	double relativeAccuracy = 1E-06
)

Parameters

pressure  DimensionfulQuantity
The pressure (compatible with Pa).
temperature  DimensionfulQuantity
The temperature (compatible with Kelvin).
relativeAccuracy  Double  (Optional)
The target relative accuracy of the result.

Return Value

DimensionfulQuantity
The mass density (SIUnit: 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.
