Convert poise to kg/m-s - Conversion of Measurement Units DYNAMIC VISCOSITY Poise (symbol: P) + centiPoise (symbol: cP) Named after the French physician Jean Louis Marie Poiseuille (1799 - 1869), this is the CGS unit of viscosity, equivalent to dyne-second per square centimetre. The poise is a unit of dynamic viscosity in the CGS system of units. In MKS system length is in meter (m), area is in square meter (m2 ), volume is in cubic meter (m3 ), time in second (s), mass is in kilogram (kg), weight (force) is in kilogram-meter per second square (kg-m/s2 ), density is in kilogram per centimeter square (kg/cm2 ), acceleration is in kilogram . Also, kinematic viscosity is more useful than dynamic or absolute viscosity for a few applications. There are various units which help us define Dynamic Viscosity and we can convert the units according to our requirement.

Examss Mock Test, Kinematic viscosity= Dynamic viscosity / Density of fluid. Steam Dynamic Viscosity, Steam . Stoke comes from the CGS (Centimetre Gram Second) unit system. Toothpaste, mayonnaise and tomato ketchup are examples of such products. The poiseuille has been proposed, but not accepted, as an SI derived unit. The kinematic viscosity tells how fast the fluid moves when a certain force is applied, while dynamic viscosity gives you information on the force needed to make the fluid flow at a certain rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. The dynamic viscosity of water at room temperature has a value of around 1.0 mPas, and it decreases as temperature increases. Summary; Viscosity and Density in Metric Units; Summary. Note that, Three types of devices are used to measure viscosity. Water - Density Viscosity Specific Weight - Engineers Edge It is denoted by the Greek symbol (v) called 'nu'. s. The following table illustrates the range of viscosity values observed in common substances. The fifth column is the typical MKS unit equation. The analogous SI unit is the Pascal second. The term 'Viscosity' in physics refers to the measure of the resistance of a fluid to gradual deformation by tensile stress (the force acting along the axis of force, which is responsible for the stretching or elongation of material) or shear stress (the external force on an object or surface area parallel to the plane or slope in which the object lies). Kinematic viscosity can be obtained by dividing the absolute viscosity of a fluid with the fluid mass density like, = / (2), = absolute or dynamic viscosity (N s/m2), In the SI-system the theoretical unit of kinematic viscosity is m2/s - or the commonly used Stoke (St) where.
