Question

Which among the following is not a pump operating parameter?

(a) Power consumption

(b) Bearing temperature

(c) Density

(d) Shaft speed

This question was addressed to me in an interview for job.

Query is from Model Testing of Partially Submerged Bodies topic in portion Dimensional and Model Analysis of Fluid Mechanics

Answer 1

Right answer is (c) Density

To explain: Every parameter plays an important role in determining the pump operation. Density is not a parameter on pump mechanical run test. Each parameter operate for nearly 10 to 15 minutes.
