How to measure kinematic viscosity
WebThe unit of measure for DV is centipoise (cP). In general, DV is related to KV with this equation: DV = KV x SG. Where: DV is the dynamic viscosity of a fluid in centipoise, cP. … WebKinematic Viscosity Converter. Kinematic viscosity is defined as the ratio of absolute or dynamic viscosity to density. Kinematic viscosity can be obtained by dividing the absolute viscosity of a fluid with its mass density. In the SI the unit is m²/s. However, the commonly used measure is the stokes (or stoke) where 1 St = 10⁻⁴ m²/s.

WebNo. 0025008218. Viscometers. The ROTAVISC viscometer series determines the viscosity of liquids in all areas of application ranging from the laboratory to quality control. The four devices measure in different viscosity ranges. Regardless of a simple or demanding viscosity measurement – the ROTAVISC viscometer delivers rapid and … WebKinematic Viscosity A measure of a fluid’s internal resistance to flow under gravitational forces. It is measured by determining the time in seconds required for a fixed volume of fluid to flow a known distance under gravity through an orifice of a calibrated viscometer at a controlled temperature.
WebTo measure kinematic viscosity, the capillary tube method is used. This method converts the time taken by the fluid to flow through the tube into kinematic viscosity. The calibration constant provided for the capillary tube is used for the time-to …
