Question:

A plate 2 mm thick and 3 m wide (normal to the page) is pulled between the walls shown in the figure at a speed of 0.5 m/s. Note that the space that is not occupied by the plate is filled with glycerin at a temperature of 20°C. Also, the plate is positioned midway between the walls. Sketch the velocity distribution of the glycerin at section A-A. Neglecting the weight of the plate, estimate the force required to pull the plate at the speed given.
