Question: A Newtonian fluid is flowing between two parallel plates of length L. The two plates are separated by a distance h. The flow is steady and only in the y direction. Sufficient forces are applied to both plates so the upper plate has a velocity VB while the bottom plate moves at vo
a. Draw a control volume and label it.
b. What is the pressure drop per unit length?
c. Derive the appropriate 2nd-order differential equation for velocity and put it in dimensionless form.
d. Calculate the dimensionless average velocity.
e. If the fluid were pseudo plastic (non-Newtonian) how would you change a, b, c, d? (Don't do it - explain.)
