Density and Enthalpy of Liquid Water

The density of liquid water of normal isotopic compositiion is given at a pressure of 101.325 kPa. The density at 100 kPa averages 0.0006 kg/m3 less. The enthalpy of liquid water relative to 0°C is based on the 1950 ICWM values, since the JANAF / CODATA values seem to be in error.
