Question

Define viscosity also find the s.I unit of coefficient of viscosity

Answer 1

Viscosity, resistance of a fluid (liquid or gas) to a change in shape, or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow. The reciprocal of the viscosity is called the fluidity, a measure of the ease of flow.

The SI unit of dynamic viscosity is the pascal-second (Pa. ... s−1). The CGS unit is called the poise (P), named after Jean Léonard Marie Poiseuille. It is commonly expressed, particularly in ASTM standards, as centipoise (cP)

Answer 2

Answer:

it is resistance of fluid to change in shape or size
