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).
