The space between two plates 20 cm×20 cm×1 cm,1 cm
apart is filled with a liquid of viscosity 1 Poise
. The upper plate is dragged to the right with a force of F=5 N
keeping the lower plate stationary. The upper plate is moving at a constant speed u
as shown in figure.
What will be the velocity in m/s
of the flow at a point 0.5 cm
below the lower surface of the upper plate if linear velocity profile is assumed for the flow ?
