Bernoulli's principle is based on which one among the following laws?

Question

Bernoulli's principle is based on which one among the following laws?

1. A. Conservation of mass
2. B. Conservation of momentum
3. C. Conservation of angular momentum
4. D. Conservation of energy (Correct answer)

Correct Answer

Option D — Conservation of energy

Detailed Solution & Explanation

The correct answer is Conservation of energy.

Key Points

• Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure.
• It is based on the Law of Conservation of Energy — the total mechanical energy (kinetic + potential + pressure energy) of a flowing fluid remains constant.
• Applications include aircraft lift and carburettors.
