HydroNomad: Pipe Sizing & Flow

HydroNomad is a professional hydraulic loss calculator and field ledger designed specifically for HVAC engineers, plumbing designers, and heating technicians. Ensure your pipe layouts, underfloor loops, and pump specifications are accurate, preventing underheating, noise, and cavitation.

Avoid complex manual equations. HydroNomad utilizes precise Darcy-Weisbach and Swamee-Jain formulas to deliver reliable calculations directly on your iPhone.

KEY FEATURES

• PROJECT LEDGER Keep all your jobs organized. Group system calculations, circuit specifications, and pressure-test logs under dedicated projects (e.g., "Cottage — Barvikha", "Scandinavia Apt. 42").

• PUMP DUTY & SYSTEM SPECIFICATION Calculate the total required pump head (H) and flow rate (Q) for your systems. Automatically sum circuit demands and factor in safety margins (default 1.2x safety multiplier).

• INTERACTIVE PIPE DIAMETER SIZING Input your target thermal power (kW) and temperature drop (ΔT) or flow rate (L/min) to find the required inner pipe diameter. Visually adjust target velocity to keep the flow within the safe velocity band (0.5 – 1.5 m/s).

• UNDERFLOOR LOOP CALCULATOR Determine precise loop lengths and fluid volumes based on room area, installation pitch (100mm to 250mm), and inner pipe diameter. Receive warnings if loop lengths exceed the recommended 120m threshold.

• ANTIFREEZE & GLYCOL CORRECTION Instantly adjust your calculations when using Propylene Glycol or Ethylene Glycol. View heat capacity changes and automatically apply flow rate multipliers and pressure drop correction factors.

• PRESSURE-TEST JOURNAL Digitally document your water system commissioning. Log test pressures, durations, and pressure drops, and attach physical pressure gauge photos directly to your records.

• TECHNICAL REFERENCE DATABASE Access instant values for pipe material roughness (PEX, Polypropylene, Copper, Steel, and Multilayer) and local resistance coefficients (fittings, valves, tees, and bends).

• COMPREHENSIVE PDF REPORTS Generate clean, professional hydraulic calculation sheets and material specifications. Export and share reports directly with clients or procurement teams.

Configure your preferred engineering units including Meters of Water Column (m H2O), Bar, or Pascal (kPa) to match your local regional standards.
