Question

Bernoulli’s equation is applicable only for _______

(a) Irrotational flow

(b) Viscous flow

(c) Inviscid, incompressible flow

(d) Compressible flow

This question was posed to me by my college professor while I was bunking the class.

My query is from Bernoulli’s Equation topic in portion Inviscid & Incompressible Flow of Aerodynamics

Answer 1

The correct choice is (c) Inviscid, incompressible flow

For explanation I would say: Bernoulli’s equation is applicable only for inviscid and incompressible flow because in inviscid flow, the viscosity is zero and hence no viscous forces acts on the body also incompressible flow means the density remains constant. The inviscid and incompressible flow reduces many fluid problems.
