The velocity profile for the flow of a Newtonian fluid between two fixed, wide, parallel plates is given by the equation u => 1-0), where V is the average velocity. The fluid has a viscosity of 1 mPa. s. Also, V=0.35 cm/s and h= 5 cm. Determine: a. the shearing stress acting on the bottom wall b. the shearing stress acting on the plane parallel to the walls and passing through the centerline (mid-plane). Sketch the profile of the magnitude of the shear stress from the centerline to the walls. c. If the density of the fluid described in this problem is 1000 kg/m", is the flow laminar or turbulent?
