The rate of outflow of liquid through an orifice does not depend upon
Correct answer: C. acceleration due to gravity
- A. radius of the orifice
- B. height of the liquid column
- C. acceleration due to gravity
- D. density of the liquid
Explanation
The rate of outflow of liquid through an orifice depends on factors such as the radius of the orifice, the height of the liquid column, and the density of the liquid. However, the acceleration due to gravity does not affect the rate of outflow through 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.
