Air vessel fitted to a reciprocating pump____________________?
Correct answer: B. Decreases the work done
- A. Increases the work done
- B. Decreases the work done
- C. Causes cavitation
- D. Results in non-uniform discharge
Explanation
An air vessel stores liquid during part of the reciprocating cycle and returns it during another part, reducing acceleration effects and smoothing the flow. This lowers the friction and acceleration work required, rather than causing cavitation or non-uniform discharge.
