If you have ever worked on an MEP project, you already know one thing: pumps are not just another piece of equipment; they are more like the heart of the water system in a building. Be it chilled water, domestic water, firefighting, or booster systems, the entire setup is based on choosing the right pump. And candidly, pump sizing does look scary at first sight, but once you break it down, it’s actually pretty logical.

In this tutorial, I am going to walk you through the process of pump sizing in a very practical, simple way-just like we explain things on-site or in the office when helping a junior engineer. No complex formulas without context; no confusing jargon-just a clean, easy-to-understand breakdown.
