Thermal Conductivity, Function of Temperature and Density

Description

The function CndTD(Temp,D,digits=9) calculates the Thermal Conductivity, k [ W m-1 K-1 ] for given Temp [K] and D [kg/m3], returning the computed thermal conductivity and an error message if an error occur.

Usage

CndTD(Temp, D, digits = 9)

Arguments

Temp

Temperature [ K ]

D

Density [ kg m-3 ]

digits

Digits of results (optional)

Details

This function calls a Fortran DLL that solves the equations developed by the International Association for the Properties of Water and Steam, valid from the triple point to the pressure of 1000 MPa and temperature of 1173.15K. http://www.iapws.org/relguide/ThCond.html

Value

The Thermal Conductivity: k [ W m-1 K-1 ] and an Error message if necessary

Examples

Temp <- 500.
D <- 838.025
Cond <- CndTD(Temp,D)
