For additional definitions, go toAbsolute (dynamic) and kinematic viscosity. Absolute or dynamic viscosity is used to calculateReynold"s Number to recognize if a fluid flow is laminar, transient or turbulent.

Online Water Viscosity Calculator

The calculator below can be supplied to calculation the fluid water dynamic or kinematic viscosity at offered temperatures.The calculation dynamic viscosity is offered as cP, mPa*s, Pa*s, N*s/m2,lbf*s/ft2 and lbm/(ft*h),while the kinematic viscosity is offered as cSt, m2/s, and ft2/s

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

Temperature

choose the really unit the temperature:

°C °F K °R

See Water andHeavy Water - thermodynamic properties.See additionally other properties of Water at varying temperature and pressure: boiling points in ~ high pressure, boil points at vacuum pressure, thickness and certain weight, Enthalpy and also entropy, heat of vaporization, Ionization Constant, pKw, of normal and heavy water, melt points in ~ high pressure, Prandtl number,Properties at Gas-Liquid Equilibrium Conditions, Saturation pressure, particular gravity, specific heat (heat capacity), details volume, thermal conductivity, heat diffusivity and also Vapour pressure at gas-liquid equilibrium.
