What is the maximum theoretical suction lift (metres) of a reciprocating pump ?
Correct answer: B. 10
- A. 5
- B. 10
- C. 50
- D. 100
Explanation
The theoretical suction lift is limited by atmospheric pressure, which supports about 10.3 m of water at sea level before vapour-pressure and flow losses are considered. Practical reciprocating-pump suction lifts are lower.
