Hot and cold water service systems - design properties, capacities, sizing and more. If values higher than 1000 cSt are required, the data given from 60 cSt can be multiplied accordingly by 10, 100, 1000 etc. The table can also alternatively be used to assign corresponding values to one another. Introduced in May 2020, designed to provide protection against low-speed pre-ignition (LSPI). The former units are no longer approved and can be converted to m²/s using Fig. Applies only to oils having an SAE viscosity grade of 0W-16. To ensure correct usage, the Stokes units and the units still currently in general use must be converted into the SI unit m 2/s. These are: degrees Engler (✮) in Germany, Saybolt seconds (S˝) in USA and Redwood seconds (R˝) in Britain. The conventional units of viscosity are unsuitable as a basis for calculation, but are still used in commerce. The Stokes unit ceased to be officially valid in 1978. The hundredth part thereof is a Centi stokes (cSt). The unit used here is m 2/s and is called – in honour of the Irish physicist STOKES – a Stokes (St). However, most measurements are still made in centistokes, e.g. Thus water at 20 ✬ has a kinematic viscosity ν = 1,002 Online calculator, figures and tables showing heat of vaporization of water, at temperatures from 0 - 370 ☌ (32 - 700 ☏) - SI and Imperial units.Kinematic viscosity (ν) designates the quotient of the dynamic viscosity of the fluid handled and its density.

Water - Density, Specific Weight and Thermal Expansion Coefficientsĭefinitions, online calculator and figures and tables with water properties like density, specific weight and thermal expansion coefficient of liquid water at temperatures ranging 0 to 360☌ (32 to 680☏). However, the most common unit of viscosity is the dyne-second per square centimeter (dyne s/cm 2) where 1 dyne 10-5 N. The output dynamic viscosity is given as Pas, Ns/m 2, cP, mPas, lb f s/ft 2 and lb m / (fth), while the kinematic viscosity is given as cSt, m 2 /s, and ft 2 /s. Using the SI units of viscosity, shear stress was in N/m 2 and shear rate was in (m/s)/m 1/s, so dynamic viscosity has units of Ns/m 2 (newton-seconds per meter squared) or Pa s (pascal-seconds). Temperature and PressureĪbsolute viscosity for water in centipoises for temperatures between 32 - 200 oF. The calculator below can be used to estimate oxygen dynamic or kinematic viscosity at given temperatures and atmospheric pressure. Vicosity is a fluid's resistance to flow and can be valued as dynamic (absolute) or kinematic. Salinity - salt content - of fresh, brackish and sea water.Īttenuation of sound in seawater vs. Solubility of oxygen in equilibration with air in fresh water and seawater (salt water) - pressures ranging 1 - 4 bar abs.
