Problem1 A thin plate is separated from two fixed thick plates by two fluids of viscosity μ₁ and μ2 (see figure). The plate spacings h₁ and h₂ are unequal. Let A be the contact area between the thin plate and each of the two fluids. Assuming a linear velocity distribution in both fluids, determine the expression of the force F required to pull the thin plate at a constant velocity V

Problem1
A thin plate is separated from two fixed thick plates by two fluids of viscosity μ₁ and μ2 (see figure). The
plate spacings h₁ and h₂ are unequal. Let A be the contact area between the thin plate and each of the two
fluids.
Assuming a linear velocity distribution in both fluids, determine the expression of the force F required to
pull the thin plate at a constant velocity V
