So the component of the flow velocity that is perpendicular to the isobar in cm/s is: V =2V cos(0)=2(10/(1+2 sin(0))) cos(0) V (10)/[1+2(1) sin(90)] = V = 3.3cm/s Assuming that the force balance considered in Q10 applies to a thin boundary layer of 0.1 cm (1 mm) thickness, compute the volume of water that converges towards the center for each second (unit: cm s) at 5 cm from the center of the drain hole (note: convergence occurs only in the boundary layer). If this converging water is removed through the drain hole at the same rate and if the tank initially contained 400 cm of water, how long does it take to drain the entire water? 5 cm # 0.1 cm Rotation: counterclockwise = 15-1 5 cm pressure gradient flow velocity friction Coriolis
