Enter the cross-sectional area and velocity of the water flow into the calculator to determine the culvert capacity. This calculator can also evaluate any of the variables given the others are known.
Culvert Capacity Formula
The following formula is used to calculate the culvert capacity.
CC = A * V
Variables:
- CC is the culvert capacity (cubic meters per second)
- A is the cross-sectional area of the culvert (square meters)
- V is the velocity of the water flow (meters per second)
To calculate the culvert capacity, multiply the cross-sectional area of the culvert by the velocity of the water flow. The cross-sectional area is determined by the size and shape of the culvert, while the velocity of the water flow is influenced by factors such as the slope of the land and the material of the culvert. The result will give the maximum volume of water that the culvert can handle per second.
What is a Culvert Capacity?
A culvert capacity refers to the maximum volume of water that a culvert, a structure that allows water to flow under a road, railroad, or similar obstruction, can handle. This capacity is determined by factors such as the culvert’s size, shape, material, and the slope of the land it’s installed on. It’s crucial to accurately calculate a culvert’s capacity to prevent flooding and other water-related damages.
How to Calculate Culvert Capacity?
The following steps outline how to calculate the Culvert Capacity.
- First, determine the cross-sectional area of the culvert (A) in square meters.
- Next, determine the velocity of the water flow (V) in meters per second.
- Next, gather the formula from above = CC = A * V.
- Finally, calculate the Culvert Capacity (CC).
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
cross-sectional area of the culvert (A) = 5 square meters
velocity of the water flow (V) = 10 meters per second
