Two immiscible Newtonian fluids are contained between infinite parallel plates. The plates are separated by distance 4h, and the top fluid layer thickness is h. The bottom layer has thickness 3h. The viscosity of the bottom fluid is three times that of the top fluid. If the lower plate moves at a constant speed of 20 m/s and the upper plate moves at a constant speed of 40 m/s, what is the average velocity within the bottom liquid layer? We...
A fluid having a viscosity u 9.35 x 104 lbf-s/ft is contained between two parallel plates, each of which has a cross section of 200 in2. The bottom plate is fixed whereas the top plate moves at a constant velocity of 4 ft/s when a shearing force is applied. The separation distance between the plates is a uniform 0.05 in. Assume the velocity distribution in the fluid is linear. Determine the following: 4. the shear stress in the fluid (lbf/in2)...
2.22. Three parallel flat plates are separated by two fluids. Plate 1 (on the bottom) is at rest. Water, viscosity 0.8007 CP at 30°C, lies between plates 1 and 2. Toluene, viscosity 0.5179 cP at 30°C, lies between plates 2 and 3. The distance between each pair of plates is 10 cm. Plate 3 moves at 3 ms. Find: (a) the velocity of plate 2 at steady-state (b) the force per unit area on plate 3 required to maintain the...
A thin flat plate is placed in between two parallel plates (top and bottom) as shown in Figure Q1. The distance separating this thin flat plate with both parallel plates is h. Apart from having a stationary top plate, the thin flat plate is moving at the speed of U and the bottom plate is moving to the left at a velocity of 0.2U. The fluid in the upper flow region (above the thin flat plate) and in the lower...
Two large flat plates are separated by a thin glycerin layer that is 5 mm thick and a temperature of 20° C. A force is applied to the top plate such shear stress = 26 Pa is generated. How fast will the top plate move relative to the bottom plate after a constant velocity is attained?
A proton enters a parallel-plate capacitor traveling to the right at a speed of 1.276 x 10-5 m/s, as shown in the figure. The distance between the two plates is 1.59 cm. The proton enters the capacitor halfway between the top plate and the bottom plate; that is, a distance r = 0.795 cm from each plate, as shown in the figure. The capacitor has a 2.75 x 10-4 N/C uniform electric field between the plates that points downward from...
please help??
b) Laminar viscous flow between two parallel plates are shown in the figure below. Both bottom plate and top plate moving in the same direction, their velocities are Un,Ut respectively and they are not equal to each other. Assume that pressure gradient between point A and point B is zero. By using Navier Stokes equations find the shear stress distribution and velocity profile for that fluid. Plot both velocity profile and shear distribution. (Show assumptions that you make...
10. Immiscible fluids Two immiscible incompressible Newtonian fluids flow together through in thedirection two lates separated by a distance H in the y-direction. Let us make thé top plate /move with ection while fixing the bottom plate. At steady state, however, there be a little slip velocity of the more dense fluid only at the lower boundary The flow constant vetocity V in the x-dir is ynidirectional and faminar. For convenience, we take that x is the flow direction and...

An incompressible fluid flows between two porous, parallel flat plates as shown in the Figure below. An identical fluid is injected at a constant speed V through the bottom plate and simultaneously extracted from the upper plate at the same velocity. There is no gravity force in x and y directions (g-g,-0). Assume the flow to be steady, fully-developed, 2D, and the pressure gradient in the x direction to be a constant P = constant).
