The head developed by a centrifugal pump is largely determined by the____________________?
Correct answer: C. Angle of the vanes and the speed of the tip of the impeller
- A. Power of the pump
- B. Nature of the liquid being pumped
- C. Angle of the vanes and the speed of the tip of the impeller
- D. Vapour pressure of the liquid
Explanation
The pump head follows from the Euler turbomachinery relation and is strongly governed by impeller peripheral speed and vane angles, which determine the change in angular momentum. Liquid nature affects losses and power, but is not the primary ideal-head determinant.
