Practice problem 3: A Newtonian fluid is in laminar flow in a narrow slit formed by
two parallel walls at a distance apart. It is understood that ,so that "edge
effects" can be ignored. Make a differential momentum balance, and obtain the
expressions for the momentum-flux and velocity distributions. Also, find the ratio of
the average velocity to the maximum velocity for this flow.
