How to Use the Flow-Based Pipe Sizing Calculator
Input Parameters
- Flow Rate: Required volumetric flow rate (L/s or GPM)
- Pipe Length: Total length of pipe run (m or ft)
- Target Velocity: Desired fluid velocity (typically 1-3 m/s for water)
- Fluid Density: Density of fluid being transported
- Viscosity: Dynamic viscosity of fluid
- Roughness: Internal surface roughness of pipe material
Calculation Results
- Diameter: Recommended internal pipe diameter
- Velocity: Actual fluid velocity in the pipe
- Reynolds Number: Dimensionless number indicating flow regime
- Friction Factor: Factor used in pressure drop calculations
- Pressure Drop: Total pressure loss due to friction
Important Considerations
This calculator provides theoretical pipe sizing based on fluid mechanics principles. Always consult applicable codes, standards, and engineering practices for your specific application. Consider factors such as available pipe schedules, pressure ratings, future expansion, and system redundancy requirements.
