Question

The liquid flowing through a series of pipes can take up__________

(a) Pipes of different diameters

(b) Pipes of the same diameters only.

(c) Single pipe only

(d) Short pipes only

This question was addressed to me during an online interview.

The doubt is from Pipes in Series topic in section Flow Through Pipes of Fluid Mechanics

Answer 1

The correct choice is (a) Pipes of different diameters

Easiest explanation: When pipes of different diameters are connected at its ends to form a pipe, this pipe so developed is called as pipes in series. They might not have to be of the same diameters. But, having the same diameters are better as it avoids the losses so developed.
