An infinite plate is moved over a second plate on a layer of liquid. For small gap width, d = 0.3 mm, we assume a linear velocity distribution in the liquid. The liquid viscosity is 0.065 Ns/m$^2$ and its specific gravity is 0.90. Lower plate is fixed and the upper plate is moving with a velocity of 0.3 m Determine: (a) The kinematic viscosity of the liquid, in m$^2$/s. (b) The shear stress on the upper plate, in N/m$^2$ (c) The shear stress on the lower plate, in Pa. (d) The direction of each shear stress calculated in parts (b) and (c).
