Calculate water flow rate in pipes based on diameter, velocity, and roughness coefficient
Water distribution systems rely on properly sized pipes to deliver water efficiently. The flow rate, diameter, and velocity are interconnected factors that determine the overall performance of the system. This calculator helps engineers, plumbers, and water management professionals determine the flow rate based on the pipe diameter, flow velocity, and pipe roughness.
The flow rate calculation is crucial for designing water supply systems, irrigation networks, and industrial piping. It ensures that the pipe can handle the required volume of water while minimizing energy losses due to friction. The Darcy-Weisbach equation forms the basis for many flow calculations, incorporating factors like pipe roughness.
Accurate pipe sizing prevents issues such as excessive pressure drop, water hammer, and inadequate supply. Factors like pipe material, age, and internal condition affect the roughness coefficient, which in turn influences the flow rate. This calculator provides a simplified approach to estimating flow rate while considering these important factors.
| Pipe Diameter (mm) | Flow Velocity (m/s) | Roughness Coefficient | Flow Rate (L/s) |
|---|---|---|---|
| 50 | 1.5 | 0.02 | 2.89 |
| 100 | 2.0 | 0.015 | 15.54 |
