Question

The total head loss for the system is equal to_________

(a) Pipe length

(b) Pipe diameter

(c) Width of the reservoir

(d) Height difference of reservoirs

This question was addressed to me in exam.

My doubt stems from Pipes in Series topic in section Flow Through Pipes of Fluid Mechanics

Answer 1

Correct choice is (d) Height difference of reservoirs

The explanation is: Total head loss for a system is equal to the height difference of the reservoirs. Height difference is denoted by the letter ‘H’. Total head loss can be equated by summing it up with all the local losses and the losses at each pipe.
