Question

Three parallel plates are placed horizontally and are separated by two fluids at 18°C, with Plate A placed at the bottom and at rest, while Plate C is placed on top and moves at 3 m/s.  Cyclohexane lies between Plate A and Plate B, spaced 3 cm apart, while water lies between Plates B and C spaced 3 cm apart.

a. What is the relation of the rate of transfer of momentum between Plates A and B, with that between Plates B and C?

b. Calculate the velocity of Plate B at steady state.

c. Suppose that the plates are spaced equally 5-cm apart, what will be the velocity of Plate B and the shear stress exerted on Plate A to maintain Plate 3 at 3 m/s?
