The formula to calculate the drainage fall is:
\[ F = \left( \frac{G}{100} \right) \times D \]
Where:
Drainage fall is the measure of vertical drop within a drainage system over a certain distance. It ensures that water flows away from structures effectively, which is crucial in civil engineering and building design. The gradient is typically expressed as a percentage, representing the ratio of the fall to the horizontal distance.
Let's assume the following values:
Using the formula:
\[ F = \left( \frac{2}{100} \right) \times 50 = 1 \text{ meter} \]
The fall would be 1 meter over a distance of 50 meters.
Let's assume the following values:
Using the formula:
\[ F = \left( \frac{5}{100} \right) \times 100 = 5 \text{ meters} \]
The fall would be 5 meters over a distance of 100 meters.
