Define coeffiecient of viscosity of a liquid. Write down its dimensional formula and MKS unit.

Text Solution

Verified by Experts

Coefficient of viscosity of a liquid may be defined as the tangential viscous force required to maintain a unit velocity gradient between its two parallel layers each of unit area.
Dimensional formula ` = [ML ^(-1) T ^(-1) ] , ` Unit ` - Nsm ^(-2) or kgm ^(-1) s ^(-1) `

When a liquid flows in a tube, there is relative motion between adjacent layers of the liquid. This force is called the viscous force which tends to oppose the relative motion between the layers of the liquid. Newton was the first person to study the factors that govern the viscous force in a liquid. According to Newton’s law of viscous flow, the magnitude of the viscous force on a certain layer of a liquid is given by F = - eta A (dv)/(dx) where A is the area of the layer (dv)/(dx) is the velocity gradient at the layer and eta is the coefficient of viscosity of the liquid. The dimensional formula for the coefficient of viscosity is :
