CT: Third Virial Coefficient (C), Function of Temperature

In IAPWS95: Thermophysical Properties of Water and Steam

Third Virial Coefficient (C), Function of Temperature

Description

The function CT(Temp,digits=9) returns the third virial coefficient, C [ m3 kg-1 ]**2, for a given Temp [K].

Usage

CT(Temp, digits = 9)

Arguments

Temp	Temperature [K]
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 second virial coefficient: C [ m3 kg-1 ]**2 and an Error Message (if an error occur: errorCodes)

Examples

Temp <- 500.
C_T <- CT(Temp)
