Constants built into iapws
Description
IAPWS and IAPWS95 contain constants relative to
ordinary water substance.
HEAVY17 is the same but for heavy water.
Usage
IAPWS
IAPWS95
HEAVY17
Format
IAPWS, IAPWS95 and HEAVY17 are numeric verctors
with with the following named elements:
"R"molar gas constant in J/K/mol.
"M"molar mass in g/mol.
"Pc"critical pressure in MPa.
"Tc"critical temperature in K.
"RHOc"critical density in kg/m^3.
"Pt"triple-point pressure in MPa.
"Tt"triple-point temperature in K.
Examples
# Convert critical density of water in mol/L
IAPWS["RHOc"] / IAPWS["M"]
