In stream line flow of liquid, the total energy of liquid is constant at
Correct answer: A. All points
- A. All points
- B. Inner points
- C. Outer points
- D. None of these
Explanation
The correct answer is All points. In streamline flow, Bernoulli's principle states that the total energy (which includes potential energy, kinetic energy, and pressure energy) of an incompressible, non-viscous fluid remains constant at all points along a streamline. This is a manifestation of the conservation of energy principle applied to fluid dynamics. The other options are incorrect because they either suggest a limited application of the principle or refer to terms that are not applicable in this context.

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.
