Pressurized pipe flow is fundamental to municipal water supply, industrial piping, and irrigation systems. This paper presents the design and methodology behind a , a computational tool that solves for unknown parameters (flow rate, diameter, pressure drop, or length) using the Darcy-Weisbach equation, Colebrook-White equation, and Manning’s formula for pressure flow. The calculator integrates iterative solvers for friction factor determination, supports multiple pipe materials, and provides real-time outputs for head loss and velocity. Validation against standard hydraulic tables shows an error margin of <2%, confirming its utility for preliminary engineering design.
