AMass
BMomentum
CEnergy
Correct Answer
DNone of these

Solution

Answer is C.

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 mechanical energy in a fluid along a streamline is the same at all points on that streamline. This requires that the sum of kinetic energy and potential energy remain constant. If the fluid is flowing out of a reservoir the sum of all forms of energy is the same on all streamlines because in a reservoir the energy per unit mass (the sum of pressure and gravitational potential) is the same everywhere.
