It is also possible to directly enter the dynamic viscosity that you want, when calculating major or minor head loss. By selecting the temperature of the fluid of your choice, you refresh the dynamic viscosity, kinematic viscosity, temperature and density of your fluid, when calculating major head loss or minor head losses. The SI unit of kinematic viscosity is m2/s. A database viscosities of fluids, gases or liquids, is incorporated into mecaflux with about 85 liquids and 35 gas, whose dynamic viscosity is given as a function of temperature. Two different fluids can have the same absolute or dynamic viscosity, but never the same kinematic viscosity. The editor of fluids allows you to set / save viscosity for a gas or liquid of your choice depending on the temperature and record it in the database Viscosity of your software. The kilogram or kilogramme, (symbol: kg) is the SI base unit of mass. In the tab " Major head loss" (pipes friction pressure losses), an editor of fluid viscosity, allows you to choose a fluid and temperature, this choice determines the dynamic viscosity. For other conversions in mass, use the mass conversion tool. Designated also Stokes (St) or centistokes (cSt).1m²/s=10 000St=1 000 000cSt The CGS unit of kinematic viscosity, stokes, was named after. Other common kinematic viscosity systems such as Saybolt Universal Seconds (SUS) and the SAE grading system can be related to the measurement of the viscosity in cSt at either 40C or 100C. Kinematic viscosity: The SI unit of kinematic viscosity is square meters per second (m 2 / s). Each term in the above equation has the units of a 'body force' (force per unit volume) with the same dimensions of a density times an acceleration. The kinematic viscosity in cSt at 40C is the basis for the ISO 3448 kinematic viscosity grading system, making it the international standard. The Reynolds number can be defined for several different situations where a fluid is in relative motion to a surface. If we divide the coefficient of dynamic viscosity by the density of the fluid, we obtain a ratio used in some formulas this report is named kinematic viscosity and its unit is m² / s. is the kinematic viscosity of the fluid (m 2 /s). This ratio varies depending on the temperature and the fluid. the legal unit of dynamic viscosity is the pascal second (pas-s) or Poiseuille (PI). The proportionality factor that binds the surface, the velocity and the distance to the frictional force, is the coefficient of dynamic viscosity n.
