pMeltT: Melting Pressure, Function of Temperature

Description

The function pMeltT(Temp,digits=9) returns the water melting pressure, pMelt [ MPa ], for a given Temp [K].

Usage

pMeltT(Temp, digits = 9)

Value

The melting pressure: pMelt [ MPa ] for regions III, V , VI and VII

The melting pressure: pMeltIh [ MPa ] for region Ih

The sublimation pressure: pSubl [ MPa ], below triple point Temperature

Error message (if an error occur)

Arguments

Temp

Temperature [K]

digits

Digits of results (optional)

Details

This function calls a Fortran DLL that solves the equations given at the Revised Release on the Pressure along the Melting and Sublimation Curves of Ordinary Water Substance (September 2011), developed by the International Association for the Properties of Water and Steam, http://www.iapws.org/relguide/MeltSub.html. It is valid from the Temperature of 256.164 [K] to the Temperature of 715 [K].

Examples

Temp <- 275.
p_Melt <- pMeltT(Temp)
