In IAPWS95: Thermophysical Properties of Water and Steam
pSatD R Documentation
Saturation Pressure, Function of Density
Description
The function pSatD(D,digits=9) returns the saturation pressure [MPa],
pSat, for given D [ kg m-3 ]: it may have two different values!
Usage
pSatD(D, digits = 9)
Arguments
D
Density [ kg m-3]
digits
Digits of results (optional)
Details
This function calls a Fortran DLL that solves the Helmholtz Energy Equation.
in accordance with the Revised Release on the IAPWS Formulation 1995 for the
Thermodynamic Properties of Ordinary Water Substance for General and Scientific
Use (June 2014) developed by the International Association for the Properties of
Water and Steam, http://www.iapws.org/relguide/IAPWS-95.html. It is valid
from the triple point to the pressure of 1000 MPa and temperature of 1273.
Value
The first saturation pressure: pSat_1 [ MPa ]
The second saturation pressure: pSat_2 [ MPa ]
An Error Message (if an error occur: errorCodes)
Examples
D <- 890.341250
p_Sat <- pSatD(D)
p_Sat
D <- 999.887406
p_Sat <- pSatD(D)
