Hydraulic Dump
Help, physics question!!?
Hydraulic engineers in the United States often use, as a units of volume of water, the acre-foot, defined as the volume of water that will cover 1 acre (where 1 acre = 43560 ft2) of land to a depth of 1 ft. A severe thunderstorm dumped 2.2 in. of rain in 30 min on a town of area 43 km2. What volume of water, in acre-feet, fell on the town?
Ans: 1970.83 Acre-feet
Explanation: Town Area = 43 Km2 = 43 * (1000m)2 = 43 * 1000 *1000 *3.3 *3.3 ft2 (1 meter = 3.3 ft)
= 468270000 ft2
Depth of rain = 2.2 inch = 2.2/12 ft
Volume of rain = Area * Depth = 85849500 ft3
Volume of rain in Acre-ft = 85849500/43560 = 1970.83
