Bernoulli's equation is an accordance with?
Correct answer: B. Law of conservation of energy
- A. Law of conservation of mass
- B. Law of conservation of energy
- C. Law of conservation of power
- D. Law of conservation of volume
Explanation
Bernoulli's equation is derived from the principle of the conservation of energy. It states that in a steady, incompressible flow of an ideal fluid with no work being performed on or by the fluid, the sum of the pressure energy, kinetic energy, and potential energy per unit volume is constant along any streamline. This reflects the law of conservation of energy. The other options are incorrect because they either refer to different principles or are not applicable in the context of fluid dynamics.

About Fluid Dynamics
Fluid flow is described through speed, pressure and density, including steady flow and the equation of continuity for conserving mass. Bernoulli's equation relates pressure, speed and height, while fluid drag and terminal velocity explain why a falling object eventually moves at constant speed when drag balances its weight.
