Question

What are the assumptions made for a fluid flow through a pipe?

(a) Fluid inertia is not taken

(b) Viscosity is not taken

(c) Volume is not considered

(d) Mass is not considered

The question was asked at a job interview.

My doubt is from Velocity of Sound or Pressure Wave in a Fluid topic in chapter Compressible Flow of Fluid Mechanics

Answer 1

The correct answer is (a) Fluid inertia is not taken

The explanation: During a fluid flow through a pipe, there are various design considerations. But, the two major assumptions are that the flow is assumed to be fully developed. Also, fluid inertia is not taken into account.
