Pipe Flow Friction Loss Calculator 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 Friction Loss Calculator
Calculates pressure drop due to friction in straight pipe runs using the Darcy-Weisbach equation. Use it when sizing pumps, designing piping systems, or troubleshooting flow resistance in water, oil, or gas networks.
- Answers
- Pressure Drop (Pa)
- Inputs
- Flow Rate, Pipe Internal Diameter, Pipe Length, Pipe Roughness, Fluid Density
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
