A thin plate moves between two stationary horizontal flat plates with a constant speed of 5m/s.

The two stationary plates are separated by a distance of 4cm, and the space between them is filled with oil with a viscosity of 0.9 N*s/m?. The thin plate has a length of 2m and a width of 0.5m.

If it moves in the midplane with respect to the two stationary plates (h1=h2=2cm), what is the force required to maintain the motion? What would this force be if h2=1cm and h1=3cm?
