Hydraulics System Design
From a flow requirement to a sized line, friction head, total dynamic head and pump power — in one workflow. Every figure is computed by the existing verified EngiMetric engines (pipe sizing, pipe flow, Reynolds, Darcy–Weisbach, pump head, pump power); the workflow chains them with explicit unit-matched data flow and design-support output only. This is not an approved final design tool — you make the decisions and the generated report documents the assumptions.

Method, assumptions & limits
Method. The required pipe size comes from flow and target velocity (v = Q/A). The workflow then selects a standard nominal bore, computes the actual velocity, checks the Reynolds regime, and applies the Darcy–Weisbach equation with a Colebrook–White friction factor as the primary friction method. Hazen–Williams is shown only as a cross-check. Total dynamic head = static lift + friction + minor losses + residual pressure; pump power follows from flow, TDH and entered efficiencies.
Assumptions. Water at ~20 °C (editable); roughness ε from reference tables (editable); efficiencies are user-stated estimates, not vendor-guaranteed; minor losses entered as equivalent head.
Limits. Single-line sizing only — networks, transient / surge analysis, and detailed hydraulics require dedicated software. Results are design-support: a licensed engineer must verify the selection against the governing jurisdictional code, the actual pipe schedule, fittings inventory, and system-specific criteria. Nothing on this page is presented as an approved final design.
