The volume of water fell on the town is 1382 acre foot.
To find the volume of water, the given values are:
Area of the town = 28 km² (square kilometer)
Time = 30 minutes
Height = 2.4 inch
The volume of water during a severe thunderstorm can be calculated as,
At first inch should be converted to meter,
1m = 39.37 inch
So, 2.4 inch = 2.4 / 39.37
= 0.0609 m
Then, we have to calculate the volume,
Formula of volume,
Volume V = Height H × Area A
= 0.0609 × 28 × 1000²
= 1705200 m³
Here, the volume should be in acre feet,
The value of, 1 m³ = 0.000810714 acre foot
so, 1705200 m³ = 1382.43 acre foot
Hence, the volume of water during a severe thunderstorm, fell on the town was 1382 acre foot.
