##### Reference no: EM13303647

The volume of water in a reservoir is often expressed using the unit of acre-foot. A volume of 1 acre-foot is the amount of water covering an area of 1 acre to a depth of 1 foot. Lake Mead is the largest man-made lake in the United States. It holds approximately 28.5 million acre-feet of water behind the Hoover Dam. If the Army Corp of Engineers desires to discharge 1.25% of the lake volume in a period of 4 days (96 h), what flow of water in gallons per second is required?
