Dfs: Saturated Liquid Density, Function of Entropy

In IAPWS95: Thermophysical Properties of Water and Steam

Saturated Liquid Density, Function of Entropy

Description

The function Dfs(s,digits=9) returns the saturated liquid density [kg m-3], Df, for given s [kJ kg-1 K-1].

Usage

Dfs(s, digits = 9)

Arguments

s	Entropy [kJ kg-1 K-1]
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 saturated Liquid density: Df [kg m-3] and an Error Message (if an error occur: errorCodes)

Examples

s <- 2.10865845
Df <- Dfs(s)
