1. The velocity distribution for the flow of a Newtonian fluid between two fixed wide, parallel
plates (see Fig.) is given by the equation:
3V
3/[ ₁ - (-)*]
where V is mean velocity. The fluid has viscosity of 0.04 lb.s/ft2. Also, V = 2 ft/s and h = 0.2 in.
Determine:
U =
(a) the shearing stress acting on the bottom wall and
(b) the shearing stress acting on a plane parallel to the walls and passing through the
centerline (midplane).
