One way to drain a liquid out of a container that has high walls is to use a siphon: a tube is placed with one end in the liquid and the other end over the wall of the container as shown on the next page. The tube is then filled with the liquid (usually by applying suction to the open end). As long as the elevation of the open end is lower than that of the top of the liquid, the liquid will flow out of the tank.

a. Derive an equation for the velocity coming out of the tube as a function of h. What happens when h approaches 0? (Assume that friction is negligible and that the top of the water in the tank is essentially stationary.)
b. What volumetric flow rate will result if h =7cm and the tube diameter equals 1 cm?
