functionenthalpyOfWater

Computes specific enthalpy of water (solid/liquid) near atmospheric pressure from temperature T

Extends from Modelica.Icons.Function (Icon for functions).

Information

Specific enthalpy of water (liquid and solid) is computed from temperature using constant properties as follows:
  • heat capacity of liquid water:4200 J/kg
  • heat capacity of solid water: 2050 J/kg
  • enthalpy of fusion (liquid=>solid): 333000 J/kg
Pressure is assumed to be around 1 bar. This function is usually used to determine the specific enthalpy of the liquid or solid fraction of moist air.
