A confined aquifer has a specific storage of 2.4 x 10-S ft and a thickness of 300 ft. How much water (in acre-ft) would it yield

Georgia [21]

Answer:

water it yield is 244290.45 ft

Explanation:

given data

specific storage SS = 2.4 × $10^{-5}$ ft

thickness b = 300 ft

water declined ΔH = 4.8 ft

radius r = 1,500 ft

to find out

How much water would it yield

solution

we know that

volume of water is

Vw = S × Area × ΔH ..............1

here S = specific storage × thickness

S = 2.4 × $10^{-5}$ × 300

S = 7.2 × $10^{-3}$

and

area = πr² = π 1,500² = 7068589.471 ft²

so

volume of water is

Vw = 7.2 × $10^{-3}$ × 7068589.471 × 4.8

Vw = 244290.45

so water it yield is 244290.45 ft
