Water And Steam Viscosity

Calculate dynamic and kinematic viscosity of water and steam from temperature and pressure.

The viscosity is calculated from temperature and density using the IAPWS R12-08 industrial equation (u2 = 1). The density can be calculated from temperature and pressure using IAPWS R7-97.

Note : There is an anomaly in the calculated viscosity and density close to the critical point. Refer to the help pages for more details (click the utility button on the data bar).
