Question $5(1$ point$)$

The Newtonian fluid shown is confined between the plate and a foxed surfice as shown in the figure below.

It's velocity profile is defined by $v=(8^{\text{'}}{y}^{\text{'}}-0\mathrm{.}3y^{\text{'}2}2)m\frac{m}{s},$ where y is in mm $.$

The plates has a surface area of $25{10}^{3}m{m}^2$ in contact with the fluid.

Take $$ as the viscosity of the fluid and suppose that $h$ is the distance between the plate and a fixed surface mm $.$

Determine the shear stress that the fluid exerts on the bottom fixed plate.
