Overflow flow rate calculator

This calculator determines the overflow flow rate in a pipe or channel based on cross-sectional area and overflow velocity. It's useful for hydraulic engineering, water management, and industrial applications.

Input Parameters

Calculation Results

Calculation Formula

Overflow Flow Rate (Q) = Area (A) × Velocity (V)

Where:
Q = Overflow flow rate [m³/s]
A = Cross-sectional area [m²]
V = Overflow velocity [m/s]

Result

Overflow Flow Rate (Q): 0.00 m³/s

Overflow flow rate calculator Calculator Usage Guide

Learn how to use the Overflow flow rate calculator calculator and its working principles

How to use the calculator

  1. Enter the cross-sectional area of the pipe or channel in square meters (m²).
  2. Enter the overflow velocity in meters per second (m/s).
  3. Click the "Calculate" button to compute the overflow flow rate.
  4. The result will be displayed in cubic meters per second (m³/s).

Applications

This calculator is useful in various fields including:

  • Water management systems design
  • Stormwater drainage systems
  • Industrial effluent disposal
  • Hydraulic engineering projects
  • Reservoir and tank overflow design

Example Calculation

For a pipe with a circular cross-section of diameter 1 meter:

Area (A) = π × (diameter/2)² = π × (0.5)² = 0.7854 m²

If the overflow velocity is 2 m/s:

Overflow Flow Rate (Q) = 0.7854 m² × 2 m/s = 1.5708 m³/s

Important Notes

The calculated flow rate assumes steady-state conditions and uniform velocity across the entire cross-section. In real-world applications, factors like turbulence, friction, and irregularities in the flow path may affect the actual flow rate.
