WebThe change in an oil’s viscosity due to a temperature change is called the viscosity index (VI). Understanding VI is important to discern whether the lubricant in question meets the asset’s requirements based on the operating temperature range. To determine an oil’s VI, the viscosity is measured at two temperatures: 40 degrees C and 100 ... Web7.9.1 Kinematic Viscosity ( ν) The kinematic viscosity is an atmospheric variable defined as the ratio between the dynamic viscosity μ and the density ρ of the fluid, i.e. (7.25) and depends on both air temperature and pressure. For air at sea level pressure and 20 °C, ρ = 1.205 × 10 −3 g cm −3 and ν = 0.15 cm 2 s −1.

Web12mm in length , This viscometer is used to determine the kinematic viscosity of the oil. From the kinematic viscosity the dynamic viscosity is determined . Theory and Definition : Viscosity is the property of fluid . It is defined as “The internal resistance offered by the fluid to the movement of one layer of fluid over an adjacent layer ‘ . WebViscometer. A viscometer (also called viscosimeter) is an instrument used to measure the viscosity of a fluid. For liquids with viscosities which vary with flow conditions, an instrument called a rheometer is used. Thus, a rheometer can be considered as a special type of viscometer. [1]
