Unit of Viscosity
Viscosities can be expressed in two different ways:
- Absolute viscosity is also known as dynamic viscosity. a standard measure of dynamic viscosity is poise. ⇒ 1 poise = 0.1 Pa.s = 0.1 N.s/m2
- Kinematic Viscosity: Kinematic viscosity is the name given to the ratio of dynamic viscosity to density, which commonly emerges. Its unit is Stoke or m2 /s (1 stoke = 0.0001 m2 /s).
Unit of viscosity is (A) m/sec (B) kg sec/m2 (C) N.sec/m2 (D) Ns2m
N.s/m2 is a unit of viscosity. Viscosity is the internal resistance to the motion of a body. It plays an important role when fluid flows at a place.
