A confided aquifer has a piezometric height of 30 feet before being pumped. The well is then pumped at 250 gallons/day for a very long time and results in a drawdown of 10 feet at the well. If the transmissivity in the aquifer is 10.0 ft2/day and the radius of the well is 0.5 feet, estimate the drawdown in feet for a well 50 feet away

Step-by-step explanation:

From the question we are told that:

Height of first draw down

Pump Discharge

Well 1 depth

Transmissivity

Radius

Well 2 depth

Generally the Thiem's equation for Discharge is mathematically given by

step-by-step explanation:

just plug in each number for x and see which ones work and don't

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
