A storm sewer is to drain an area of 40 acres. Design the diameter of this storm sewer if it is to carry away rain falling at a rate of 2 inches per hour during a period of 30 minutes, the time needed for the entire drainage area to become tributary to the storm sewer. The required minimum velocity of flow is the cleaning velocity of the sewer, which is 3 feet per s
