Question

Which of the following statements regarding well discharge are true?
A. It increases with drawdown
B. It increases with well diameter
C. It is affected by diameter but not drawdown
D. It decreases with drawdown
Choose the correct answer from the options given below:

• A. C only
• B. A and B only
• C. B and D only
• D. B and C only

Hint:

- Discharge is directly proportional to drawdown (\(Q \propto s\)).
- Discharge is logarithmically proportional to well radius (\(Q \propto 1/\ln(R/r_w)\)).
Therefore, increasing the drawdown is much more effective at increasing yield than digging a wider well.

Answer 1

The Correct Option is B
