According the stokes theorm the viscous force on a spherical body inside a fluid is 6π(eta)RV where eta is coefficient of viscosity R is radius of body and V is velocity of the body inside the fluid

palakgusain18: sorry but i want formula of viscous force

palakgusain18: I don't wantbtontheory

palakgusain18: I don't want theorem

Anonymous: F= (eta)A dv/dx where A is area of the layer, and dv/dx is is velocity gradient

palakgusain18: what is (eta)

palakgusain18: ???

Anonymous: Eta is coefficient of vis

Explanation:

Viscosity is the measure of resistance to deformation in a liquid. It is similar to the resistance in solid.
It elates the viscous stresses in a material to the rate of change of a deformation.
The formula of viscous force is given by :

$F=-\eta A\dfrac{dv}{dz}$

Here,

$\eta$ is viscosity

A is cross sectional area

$\dfrac{dv}{dz}$ is rate of shear deformation
