1. Two large fixed parallel planes are 12mm apart. The space
between the surfaces is
filled with oil viscosity 0.972 N.s/m2
. A flat thin plate 0.25m2
area moves through the
oil at a velocity of 0.3 m/s. Calculate the drag force:
i. When the plate is equidistant from both the planes, and
ii. When the thin plate is at a distance of 4 mm from one of the
plane surfaces.
