Two large fxed parallel planes are 12 mm apart. The space between the surfaces Example is filled with oil of viscosity 0.972 N.s/m². A flat thin plate 0.25 m² area moves through the oil at a velocity of 0.3 m/s. Calculate the drag force: () 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.

Question
Two large fixed parallel planes are 12 mm apart. The space between the surfaces Example is filled with oil of viscosity 0.972 N.s/m². A flat thin plate 0.25 m² area moves through the oil at a velocity of 0.3 m/s. Calculate the drag force: (1) 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. Fixed parallel plane 6 mm Plate 0.3 m/s F 6 mm 12 mm
