Note that the pressure is patm everywhere. (b) Because viscous effects are negligible, there is no way for the air to exert a force on the plate in the tangential (z) direction. Using the coordinate system in the figure, find A₂ and A3 in terms of A₁ and 0. (c) For V₁ = 50 m/s, A₁ = 5 x 10-4 m², and 0 = 60°, find the force required to hold the plate in place.

Oil Coating: A long, continuous belt is pulled upwards through a chemical oil bath at velocity V0. The belt has rectangular cross-section and has length (L), width into the paper (W). The belt picks up a film of oil of thickness h, density ρ, and dynamic viscosity μ. Gravity g tends to make the oil drain down, but the movement of the belt keeps the fluid from running off completely. Assume fully developed, steady, laminar, incompressible and two-dimensional flow of oil to answer the following questions. Assume that no pressure gradient is needed in the vertical direction to drive the film flow. Also assume that the shear stress at the air-oil interface is zero (free shear condition). Assume no-slip condition for the fluid in contact with the moving belt. Justify any other assumptions you may make. Show all steps.

Ex (3): Consider the flow of water between two vertical parallel plates at 30 degrees Celsius. The distance between the plates, 2B, is small in comparison to the plates' length (l) and width (w). The plate on the left side is fixed, while the plate on the right is rising upward at a tiny velocity U. Given the length of the plates, the flow of water between them is considered to be laminar and fully developed. Find the shear stress profile of the flowing water using shell momentum balance method and sketch the profiles.
