You would like to empty the in-ground pool in the back yard but the drain at the bottom of the pool is no longer functional. Given the dimensions in Fig. 6.43, determine the flow rate from the pool at the instant shown if the hose has an inside diameter of 0.5 in. What had to happen to initiate flow from the drain hose? What will happen to the flow rate as the level of the pool drops?

1 ft Hose length = 100 ft 10 ft 13 ft 75 ft
