Kinematic Viscosity is momentum diffusivity. The viscosity of water at is 0.01 Poise or 1.0 centipoise.ĭynamic Viscosity is absolute viscosity or simply viscosity. Sometimes a unit of viscosity as centipoise is used where If viscosity is given in Poise, it must be divided by 10 to get its equivalent numerical value in SI units. One Newton = one kg (mass) x one (m/s2)(acceleration) The numerical conversion of the unit of viscosity from MKS unit to CGS unit is given below: The unit of viscosity in CGS is also called Poise which is equal to Is also known as Pascal and is represented by ‘Pa’. In MKS system, the force is represented by kgf and the length is represented by metre (m), in CGS system, the force is represented by dyne and the length is represented by cm and in SI system the force is represented by Newton (N) and the length is represented by meter (m). The units of viscosity is obtained by putting the dimensions of the quantities in equation (i) Viscosity is also defined as the shear stress required to produce unit rate of shear strain. is the rate of shear strain or rate of shear deformation or velocity gradient. Where (called mu), is the constant of proportionality and is known as the coefficient of dynamic viscosity or only viscosity.
