Purpose of air lift pump is to____________________?
Correct answer: C. Lift water from a well by using compressed air
- A. Compress air
- B. Lift compressed air
- C. Lift water from a well by using compressed air
- D. Lift air under negative pressure
Explanation
An air-lift pump injects compressed air into a liquid column, reducing its average density so the water rises through the delivery pipe. It does not lift compressed air itself.
