LoopQP

LoopQP is an engineering calculation software designed to analyse flow distribution, and head losses in pipe networks of any configuration — including looped, tree (branched), and series systems.

It automates classical hydraulic solving methods using Hardy-Cross and modern numerical approaches to quickly converge on balanced flows and pressures throughout the network. Ideal for mechanical, civil, and building services engineers who need fast and accurate hydraulic calculations without complex simulation packages.

LoopQP helps engineers design or verify water piping networks used in:

HVAC ducting systems

Plumbing and water supply networks

Industrial process piping

Any network with loops, branches, or multiple paths

With a clean interface and CSV-friendly data input, LoopQP allows engineers to quickly build pipe networks, run iterative balancing, and generate results for flow, velocity, Reynolds number, pressure loss, and more.

Key Features:

Calculate flow and pressure for looped, branched, and series pipe networks

Uses Hardy-Cross method, Darcy-Weisbach head loss equation and modern numerical solvers
