Pipe Flow Velocity Calculator vs Pipe Flow Friction Loss 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 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
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
