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)...

Consider a Couette flow between two flat plates: One plate is stationary, while the other plate is moving with a velocity vo; the distance between the plates is h. Realize that the density and the viscosity of the fluid are roughly constant. You may also presume that the velocity is mostly unidirectional, solely varying in its perpendicular direction. In turn, formulate and solve the differential equation which governs the velocity profile!
