Water - Dynamic (Absolute) and Kinematic Viscosity vs. One figure showing relative viscosity with variations in pressure and temperature is also included. The figures and tables below shows how water viscosity changes with temperature (☌ and ☏) at water saturation pressure (which for practicle use, gives the same result as atmospheric pressure at temperatures < 100 ☌ (212☏)).

See also dynamic and kinematic viscosity of air, ammonia, benzene, butane, carbon dioxide, ethane, ethanol, ethylene, methane, methanol, nitrogen, oxygen and propane See also other properties of Water at varying temperature and pressure : Boiling points at high pressure, Boiling points at vacuum pressure, Density and specific weight, Enthalpy and entropy, Heat of vaporization, Ionization Constant, pK w, of normal and heavy water, Melting points at high pressure, Prandtl number, Properties at Gas-Liquid Equilibrium Conditions, Saturation pressure, Specific gravity, Specific heat (heat capacity), Specific volume, Thermal conductivity, Thermal diffusivity and Vapour pressure at gas-liquid equilibrium. See Water and Heavy Water - thermodynamic properties. Note! Temperature must be within the ranges 0-370 ☌, 32-700 ☏, 273-645 K and 492-1160 °R to get valid values. While the kinematic viscosity is given as cSt, m 2 /s, and ft 2 /s The output dynamic viscosity is given as cP, mPa*s, Pa*s, N*s/m 2 ,lb f *s/ft 2 and lb m /(ft*h), The calculator below can be used to calculate the liquid water dynamic or kinematic viscosity at given temperatures. Absolute or dynamic viscosity is used to calculate Reynold's Number to determine if a fluid flow is laminar, transient or turbulent. įor further definitions, go to Absolute (dynamic) and kinematic viscosity. The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress.
