What is the Difference Between Flow Rate and Velocity?

Rate of flow, or simply flow, is the quantity of water, for example, that flows in a tube or other medium, in an interval of time. Examples: 2 kg of water per second, or 100 cubric meters of air per minute. Velocity is how fast the water, air or other fluid is moving in a tube or other medium.

How to Calculate Water Flow Equation?
