Question:
13. The velocity distribution over a plate is given by u = 2/3y-y^2 in which u is the velocity in m/sec at a distance of y m above the plate. Determine the shear stress at y = 0, 0.1 and 0.2 m. Take p = 6 poise.
[ 0.4, 0.028 and 0.159 N/m]
14. In question 13, find the distance in metres above the plate, at which the shear stress is zero.
[ 0.333 m]
