Water Property Calculator
This calculator calculates thermodynamic properties for water
as function of pressure and temperature.
It is capable of calculating the properties density,
specific isobaric heat capacity, specific isochoric heat capacity,
specific enthalpy, specific entropy, specific internal energy,
dynamic viscosity and kinematic viscosity as function of pressure and temperature.
Temperature input is in degree Celsius and the pressure is absolut pressure
in bar i.e. bar(A). The calculator is only valid for water on liquid form.
IAPWS-IF97 industrial formulation and IAPWS R12-08 developed by
The International Association for the Properties of Water and Steam (IAPWS)
has been used as source when making the calculator. IAPWS are by no means assosiated with this site nor have they
verified our implementation and the results from the calculator.
