A. An incompressible, viscous, Newtonian fluid flows in a channel between two fixed plates as shown. Which velocity distribution has the larger mass flow rate? Which velocity distribution creates the

smaller magnitude shear stress on the bottom plate B The viscosity of common liquids (water, seawater, oils) generally decreases with increasing temperature. C. The velocity profile in a simple shear flow between two horizontal plates is given by u(y) = Vy/h,where y is measured from the bottom plate and h is the distance between the plates, and V is directed in the (+) x-direction to the right. Which of the following are true: I.The fluid film must be thin. П.The shear force of the fluid on the top plate is directed towards the left. III.The flow is unsteady. IV.The shear stress is constant throughout the fluid (e.g. at any location y). IV.The shear stress is constant throughout the fluid (e.g. at any location y). D. A viscous, Newtonian fluid is placed between two plates separated by a very small distance. The plates move with velocities Vị and V2 as shown. Clearly draw in the velocity profile that would result in the fluid.
