The flow from two of the troughs described in Problem 14.20 passes into a sump, from which a round common clay drainage tile carries it to a storm sewer. Determine the size of tile required to carry the flow (500 gal/min) when running half full. The slope is 0.1 percent.

Problem 14.20

A square storage room is equipped with automatic sprinklers for fire protection that spray 1000 gal/min of water. The floor is designed to drain this flow evenly to troughs near each outside wall. The troughs are shaped as shown in Fig. 14.23. Each trough carries 250 gal/min, is laid on a 1-percent slope, and is formed of unfinished concrete. Determine the minimum depth h.
