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

Options

A. Conservation of mass
B. Conservation of momentum
C. Conservation of angular momentum
D. Conservation of energy

Answer

D

Explanation

Bernoulli's principle is based on the principle of conservation of energy. This states that, in a steady flow, the sum of all forms of energy in a fluid along a streamline is the same at all points on that streamline. This requires that the sum of kinetic energy, potential energy and internal energy remains constant.
