The speed of efflux can be written as
Correct answer: A. √2gh
- A. √2gh
- B. gh
- C. 2pgh
- D. √pgh
Explanation
The speed of efflux, or the velocity with which a fluid exits an orifice under the influence of gravity, is given by the Torricelli's theorem. The correct formula for the speed of efflux is 2gh , where g is the acceleration due to gravity and ℎh is the height of the fluid above the orifice.

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.
