The Ultimate Guide to Centrifugal Pumps: Types, Design, and …
Flow Rate Calculation. To determine the flow rate needed for your application, use the following equation: Where: Area is the cross-sectional area of the pipe (m 2).; Velocity is the speed of the fluid in the pipe (m/s).; It is important to note, that in many applications there is a range of velocity that is required for Certain pumping systems and piping networks.
