Question

What are the limitations of Bernoulli's theorem?

Answer 1

Hi

Here is your answer,

The Four limitations of Bernoulli's Theorem is :-

1. Bernoulli's equation ideally applies to fluids with zero viscosity or non-viscous fluids.

2. The fluids must be incompressible, as the elastic energy of the fluid is also not taken into consideration.

3. Bernoulli's equation is applicable only to streamline flow of a fluid. It is not valid for non-steady or turbulent flow.

4.It applies ideally to the fluids with zero velocity and non -viscous fluids but not to be viscous fluids.


Hope it helps you !

Answer 2

Answer:

LIMITATIONS:-)

1》 Bernoulli's equation has been derived on the assumption that there is no loss of energy due to friction. But in practice, when fluid flow, some of their kinetic energy gets converted into heat due to the work done against the internal forces of friction or viscous forces.

2》 Bernoulli's equation is applicable only To incompressible Fluids because it does not take into account the elastic energy of the fluid.

3》 Bernoulli's equation is is applicable only to streamline flow of fluid and not when the floor is turbulent.

4》 Bernoulli's equation does not take into consideration the angular momentum of the fluid. So it cannot be applied when the fluid flows along a curved path.
