S.I. Unit of rate of flow of a fluid :
Correct answer: C. Meter 3 / sec
- A. Meter / sec
- B. Meter2 / sec
- C. Meter 3 / sec
- D. Meter 2 / sec2
Explanation
Meter3 / sec is the unit of volume per second. Volume is the amount of space that is enclosed by a three-dimensional figure, and it is measured in cubic meters. For example, if a cube has a volume of 10 cubic meters, then its volume per second is 10 m3/s.

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.
