10. Two large fixed parallel planes are 240 mm apart.
The space between the surfaces is filled with oil
of viscosity 0.81 N.s'm. A flat thin plate 0.5 m
area moves through the oil at a velocity of 0.6
m's. Calculate the drag force (1) when the plate
is equidistant from both the planes, and (if) when
the thin plate is at a distance of 80 mm from one
of the plane surfaces.
