An infinite plate is moved over a second plate on a layer of liquid as shown. For small gap width,

d, we assume a linear velocity distribution in the liquid. The liquid viscosity is 0.65 centipoise and its specific gravity is 0.88. Determine:

(a) The absolute viscosity of the liquid, in lbf s ft².

(b) The kinematic viscosity of the liquid, in m² s.

(c) The shear stress on the upper plate, in lbf ft².

(d) The shear stress on the lower plate, in Pa.

(e) The direction of each shear stress calculated in parts

(c) and (d).
