Pipe Flow Calculator (Hazen-Williams) vs Pipe Flow Velocity Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Pipe Flow Calculator (Hazen-Williams)
Determine water flow rate and velocity in pressurized pipes using the Hazen-Williams empirical equation. Ideal for civil engineers sizing water mains, irrigation lines, or fire-suppression systems.
- Answers
- Flow Rate (L/s)
- Inputs
- Pipe Diameter, Pipe Length, Head Loss, Hazen-Williams Coefficient
Pipe Flow Velocity Calculator
Calculates the average flow velocity of fluid in a circular pipe given a volumetric flow rate and pipe diameter. Use it when sizing pumps, checking design velocities, or troubleshooting pipe systems.
- Answers
- Flow Velocity (m/s)
- Inputs
- Flow Rate, Pipe Diameter
