### What is Meant by Flow Rate?

In Physics, the flow rate is defined as the volume of liquid which flows through an area per unit second. Generally, the flowing liquid is characterized by a quantity called the flow rate. The SI unit of flow rate is Cubic meter/second. In a closed region or in the pipe, the flow rate is expressed in terms of the velocity of the flowing liquid through the given cross-sectional area. Thus, the formula to calculate flow rate is given by

Flow Rate = Flow Area × Flow Velocity
