Chapter 1, Problem 1.48P

A thin plate is separated from two fixed plates by very viscous liquids μ 1 and μ 2 , respectively, as in Fig. P1.48. The plate spacings h1and h2arc unequal, as shown. The contact area is A between the center plate and each fluid. (a) Assuming a linear velocity distribution in each fluid, derive the force F required to pull the plate at velocity V. (b) Is there a necessary relation between the two viscosities, μ 1 and μ 2 ?
