Question: with the given information of the previous problem i need...

Question details

1. Consider a channel with height h and with y 0 located at the lower wall. Starting from the two-dimensional, incompressible, viscous equations of motion, given below, show that the equation for the x-component of velocity in a developed channel flow can be written du 1 dp -constant Show all your assumptions. You can neglect gravitational effects. If the upper wall of the channel in Problem 1 moves in the x-direction with velocity U, and in the presence of a pressure gradient, show that the x-component of velocity can be written, 2. where, h2 dp 2puU dx 3. At what value of z does the velocity on the channel centerline equal zero? Is this a positive or negative pressure gradient?
With the given information of the previous problem, I need the solution to number 3 only.
