The Importance of the Culvert Flow Calculator

Culverts, often unseen beneath roads and railways, play a vital role in managing water flow. The Culvert Flow Calculator serves as a crucial tool in hydraulic calculations, enabling engineers to determine the volumetric flow rate through a culvert. This information is fundamental in ensuring the efficient functioning of culverts, preventing flooding, and safeguarding infrastructure from potential damage.

How to Use the Culvert Flow Calculator

Using the Culvert Flow Calculator is a straightforward process:

  1. Cross-sectional Area (sq ft): Enter the cross-sectional area of the culvert.
  2. Flow Velocity (ft/s): Specify the velocity of water flow through the culvert.
  3. Calculate Culvert Flow (Q): Click the button to obtain the volumetric flow rate.

The calculator applies the formula Q = Cross-sectional Area * Flow Velocity, providing a valuable metric for hydraulic engineers.
