Pipe Flow Calculator (Hazen-Williams) vs Pipe Flow & Pressure Drop 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 & Pressure Drop Calculator
Calculates pressure drop along a pipe using the Hazen-Williams equation, accounting for pipe material, flow rate, diameter, length, and elevation change. Use it to size water distribution pipes, fire suppression systems, and irrigation lines.
- Answers
- Pressure Drop (psi)
- Inputs
- Pipe Diameter, Pipe Length, Flow Rate, Pipe Material, Elevation Change
