= Three parallel plates having the same surface area A, are positioned as shown in the figure. The upper two plates are moving at V and V velocities while the bottom plate is fixed. A fluid having viscosity of u is contained between the plates. You are given that hi 1.0 mm, h2 = 2.0 mm, V = 2.0 m/s, F = 1 N, = 0.027 Pa.s, and A = 0.4 m. Assuming linear velocity variation between plates; a) Determine the velocity, V of the middle plate. b) Draw the shear stress diagram on the figure. c) Find the force F to make the upper plate move at the given velocity V. hi=1 mm h= 2 mm V-2 m/s, Fi=? V=?, F IN Fixed plate
