Pressure / Nozzle / Diesel Pump Calculator
2-row / 6-nozzle water spraying calculator for a 1,000 L tank, diesel water pump, header, branches, nozzle flow, pipe loss, TDH, HP, warnings, export, and marketplace assist.
1. System Layout
Tank, rows, nozzles, symmetry, and equal flow assumption.
2. Fluid Properties
Hazen-Williams is mainly for water; non-water fluids remain calculable but warned.
3. Nozzle Inputs
Known-flow presets are useful when catalogue flow is available. Calculated mode requires orifice diameter.
4. Pipe Inputs
Internal diameters are treated as entered. Converted diameters are shown after calculation.
5. Geometry / Pipe Length Inputs
Branch rows are parallel; the design path uses one branch-row loss, not both added together.
6. Loss Factors / Fittings
Estimated K values are approximate. Manufacturer pressure-drop data is preferred for filters and strainers.
7. Pump Inputs
Without a pump curve, pressure/flow/HP checks are estimates rather than a verified operating point.
8. Marketplace Component Assist
Manual fallback works offline by generating search links and accepting manual candidate specs. API proxy and n8n/MCP modes need a configured endpoint.
Manual candidate entry
9. Formula Explanation
Equations are shown in practical engineering form, with SI internal units.
10. Export / Print
Exports include inputs, outputs, warnings, assumptions, selected marketplace candidate, calculation mode, and the engineering notice.
