Lw hydraulic engineers in the united states often use, as a unit of volume of water, the acre-foot, defined as the volume of water that will cover 1 acre of land to a depth of 1 ft. a severe thunderstorm dumped 2.0 in. of rain in 30 min on a town of area 26 km2. what volume of water, in acre-feet, fell on the town?

volume of water is 1066.50 acre feet

Explanation:

given data

dia = 2 in = 0.166 feet

area = 26 km² = 26 × 247.105 acre = 6424.73 acre

to find out

volume of water

solution

we know volume of water is express as

volume = area × dia     1

put here value in equation 1

volume = 6424.73 acre × 0.166 feet

volume = 1066.50

so volume of water is 1066.50 acre feet
