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 $\=T 10.0 ft2/day$

Radius $r=0.5$

Well 2 depth $d_2=50ft$

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

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

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

$1151.293=2*\pi 10 (10-d_2)$

$d_2=-8.32ft$
