The fluid flowing in fig. 1-3 has an absolute viscosity (u) of 0.0010 Ib.s/ft^2 and specific gravity of 0.913. calculate the velocity gradient and intensity of shear stress at the boundary and at points 1 in, 2 in, and 3 in from the boundary, assuming (a) a straight-line velocity distribution and (b) a parabolic velocity distribution. The parabola in the sketch has its vertex at A and origin at B.
