Explain Bernoulli’s theorem with neat sketch. State its two important assumptions.

1 Answer

Answer :

This theorem states that whenever there is continuous flow of liquid the total energy at every section remains same provided that there is no any addition or loss of energy.

Let us consider a conduit having 2-sections.

Now, By using Bernoulli’s Theorem,

Total head at section 1 = Total head at section 2

Assumptions: 

1. The fluid is ideal.

2. The flow is steady & continuous.

3. The flow is incompressible.

4. Velocity is uniform over the cross section.

5. The flow is irrotational.
