Unformatted text preview: 1.28 A Newtonian fluid having a specific gravity of 0.92
and a kinematic viscosity of 4 X 10“ m2/s flows past a
fixed surface. Due to the no-slip condition, the velocity at
the fixed surface ismzero (as shown in Video V1.2), and the
velocity profile near the surface is shown in Fig. Pl.28. De-
termine the magnitude and direction of the shearing stress
developed on the plate. Express your answer in terms of U
and 6, with U and 8 expressed in units of metersper sec-
ond and meters, respectively. FIGURE P1.28 ...
