The velocity of the flow of liquid through an orifice at the bottom of a tank depends upon
Correct answer: D. both b and c
- A. density of liquid
- B. height of liquid above the orifice
- C. gravity
- D. both b and c
Explanation
Torricelli's theorem links the speed of eflux out of a container's bottom. It is given as v= √2ghSo, the velocity depends on height and the gravity

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.
