In the thin boundary layer of the rotating tank, there is a three-way balance of forces. Isobars form concentric loops in the boundary layer, pressure decreasing toward the center (drain hole). At 5 cm from the center of the drain hole, the inward acceleration due to pressure gradient force is 10 cm s (see figure below). Accelerations associated with the frictional force and the Coriolis force are yV and 2QV, respectively, where y = Q = 1s and V is the magnitude of the flow velocity. Assuming the three accelerations balance vectorially, compute V and the component of the flow velocity that is perpendicular to the isobar in the unit of cm s.
