Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

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.
