Consider steady, incompressible, laminar flow of two Newtonian fluids sandwiched between two infinitely large parallel plates. The fluids have different densities, different viscosities, and they form a well-defined interface (i.e., they are immiscible). The lower plate is stationary whereas the upper plate moves to the right at constant velocity U. There is no applied pressure gradient pushing the fluid through the gap. The fluid is set into motion due to the movement of the upper plate. Determine the velocity at the interface in terms of U, µ1, and 42. moving plate U h Fluid 1 Fluid 2 fixed plate

(include units with answer) A 0.11 inch diameter hole is punched in the bottom of a 2.8 inch diameter can. The can is open at the top and contains 11 oz of liquid. What is the initial velocity Format C of the liquid coming out of the hole? (include units with answer) Previous Next

Suppose that a force equal to 7 N is pushing the piston as in (figure 1) and it attains a steady state speed of 3.5 m/s. find the viscosity of the fluid to be used in the system.

Question A2 Figure QA2 is a schematic view of a river flow down an infinite hill with a constant angle of 0. Assume the viscosity and density of water are μ and prespectively. Furthermore assume in this motion the depth of the river remains unchanged and pressure is constant. a) List all the assumptions that you make in order to simplify the conservation of mass and N-S equations. b) Derive and list the simplified equations. c) Find a general solution to the velocity distribution across the river depth and then by applying the appropriate boundary conditions find an expression for the velocity profile. d) Determine the depth of the river in terms of volume flow rate Q per unit width.
