Question 5 [20 marks) Consider Coutte flow, which occurs when we have a fluid suspended between two parallel plates, one of which is moving and the other of which is stationary. The velocity profile between these two plates is linear. We have water between these two plates and distance separating them of 1 mm. Given this information: (a) What is the force exerted on the stationary plate per m2 if the moving plate has a velocity of 0.1 m/s in...

, (20 pts) The Newtonian fluid is confined between an upper plate and a bottom f If its velocity profile is defined by u s(9y-0.1y3) rn m/s , where y is in mm, (a) determine the shear stress that the fluid exerts on the upper plate and bottom fixed surface and (b) indicate the direction of each shear stress. Take the fluid viscosity A0.482 N s/m2.

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 Newtonian body wash undergoes steady shear between two horizontal parallel plates. The lower plate is fixed, and the upper plate of 1kg moves with constant velocity of 20 m/s. The distance between the plates is constant at 5 mm. The area of the upper plate in contact with the fluid is 0.5 m2 . a) What is the viscosity of the product and b) the momentum diffusivity if its density is 1010 kg/m3?

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...
