Water - Specific Heat vs. Temperature

Sponsored Links

Specific heat (C) is the amount of heat required to change the temperature of a mass unit of a substance by one degree.

When calculating mass and volume flow in a water heating systems at higher temperature - the specific heat should be corrected according the figures and tables below.

The specific heat is given at varying temperatures (°C and °F) and at water saturation pressure (which for practical use, gives the same result as atmospheric pressure at temperatures < 100 °C (212°F)).

  • I sochoric specific heat  (Cv ) for water in a constant-volume , (= isovolumetric or isometric ) closed system.
  • Isobaric specific heat (Cp ) for water in a constant pressure (ΔP = 0) system.

Online Water Specific Heat Calculator

The calculator below can be used to calculate the liquid water specific heat at constant volume or constant pressure and given temperatures.
The output specific heat is given as kJ/(kmol*K), kJ/(kg*K), kWh/(kg*K), kcal/(kg K), Btu(IT)/(mol*°R) and Btu(IT)/(lbm *°R)

Note! Temperature must be within the ranges 0-370 °C, 32-700 °F, 273-645 K and 492-1160 °R to get valid values.
