The velocity distribution across a section of two fixed parallel plates having viscous flow is given by ____
Where \(\frac{{\partial P}}{{\partial x}} = \) pressure gradient along the length of the plate
y = point of consideration from the lower fixed plate
t = distance between the two fixed parallel plates
