Viscous force exerted by the liquid flowing between two plates in a streamline flow depends upon the

We know that viscous force,

$\mathrm{F}=-\mathrm{\eta }\times \mathrm{A}\times \frac{\mathrm{dv}}{\mathrm{dy}}$

The velocity gradient in the direction perpendicular to the plates determines how much viscous force the liquid exerts when flowing between two plates in a streamline flow. the viscous force is also dependent on Area of the plate and the coefficient of viscosity.
