Velocity distribution equation for Couette flow

Solution:

In this equation, the y = 0 axis lies equidistant between the plates at a distance h/2 from the two plates, p is the pressure variable and n is the dynamic viscosity term. The maximum and average velocities are, respectively [2014 : 2 Marks, Set-II]

Answer:

Solution:

Velocity expression for a laminar flow between two parallel plates is,
