Consider steady, incompressible, laminar flow of a Newtonian fluid in the narrow gap between two infinite parallel plates. The top plate is moving at speed V, and the bottom plate is moving in the opposite direction at speed V. The distance between these two plates is h, and gravity acts in the negative z-direction. There is no applied pressure other than hydrostatic pressure due to gravity. Calculate the velocity and estimate the shear stress acting on the bottom plate Moving...

Two horizontal plates with infinite length and width are separated by a distance H in the zdirection. The bottom plate is moving at a velocity vx=U. The incompressible fluid trapped between the plates is moving in the positive x-direction with the bottom plate. Align gravity with positive z. Assume that the flow is fully-developed and laminar. If the systems operates at steady state and the pressure gradient in x-direction can be ignored, do the following: 1. Sketch your system. 2....

An incompressible, viscous fluid is placed between horizontal, infinite, parallel plates as shown below. The two plates move in opposite directions with constant velocities U 10 m/s and U2 = 5 m/s as shown. The pressure gradient in the x direction is zero and the only external force is gravity (in the y-direction). Use the Navier-Stokes equations to determine where the fluid velocity is zero (in terms of a fraction of b, i.e. 0.75 for y-75% of b) Enter Number...
