gradient in such a way that the net forward discharge across any section is zero. Consider ‘U’ be the velocity of the moving plate.

(i) Find out the point where minimum velocity occurs and its magnitude

(ii) Draw rough sketch of velocity distribution across any section

In the given case of flow, the velocity distribution is given by

u=$\frac{U}{b} y-\frac{1}{2μ} \frac{∂p}{∂x} (by-y^2 )$………(1)

And the discharge per unit width,

q=$\frac{Ub}{2}-\frac{b^3}{12μ} \frac{∂p}{∂x}$………(2)

Net forward discharge,

q=0…………(given)
