Pipe Sizing Calculator
Calculate optimal pipe diameters for water supply systems based on flow rate, velocity limits, and pressure drop. Supports copper, PVC, PPR, galvanized steel, and HDPE pipes with Hazen-Williams friction calculations.
Volume flow rate in liters per second
Recommended velocity: 0.6 - 2.5 m/s
Hazen-Williams coefficient affects friction loss
Optional: Override the default max velocity for your fluid type
Enter flow parameters and click Calculate to see pipe sizing results
Notes:
- Calculations based on Hazen-Williams formula for friction loss
- Reynolds number determines flow regime (laminar/turbulent)
- Velocity should be within recommended range to prevent noise and erosion
- Consider pressure requirements and system constraints
- For fire systems, consult local codes for minimum requirements
