Question

Bernoulli's equation cannot be applied when the flow is

Answer 1

To answer this question, we must understand the assumptions of Bernoulli's principle.

The assumptions are as follows :

1.) The flow must be steady.

That is, the fluid properties of the fluid such as density and velocity at a point cannot change with time.

2.) The flow must be incompressible.

Even though pressure varies, the density must remain constant along a streamline.

3.) Friction by viscous forces has to be negligible.
