Three parallel flat plates are separated by two fluids. Plate 1 (on the bottom) is at rest. Water, viscosity 0.8007 cP at 30 degree C, lies between plates 1 and 2. Toluene, viscosity 0.5179 cP at 30 degree C, lies between plates 2 and 3. The distance between each pair of plates is 10 cm. Plate 3 moves at 3 m s-1 Find: the velocity of plate 2 at steady-state the force per unit area on plate 3 required to maintain the 3 m s-1 velocity.
