A confided aquifer has a piezometric height of 30 feet before being pumped. The well is then pumped at 250 gallons/day for a ver
Karo-lina-s [1.5K]

Answer:

d_2=-8.32ft

Step-by-step explanation:

From the question we are told that:

Height of first draw down h=30

Pump Discharge Q=250gallons/day

Well 1 depth d_1=10ft

Transmissivity\=T 10.0 ft2/day

Radiusr=0.5

Well 2 depth d_2=50ft

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

 Q=\frac{2\piT(h_2-h_1)}{ln(\frac{r_2}{r_1})}

 250=\frac{2*\pi 10 (10-d_2)}{ln(\frac{50}{0.5})}

 1151.293=2*\pi 10 (10-d_2)

 d_2=-8.32ft
