Fall Per Foot Formula
The following formula is used to calculate the fall per foot for a given total fall and total distance.
Variables:
- F is the fall per foot (ft/ft)
- T is the total fall (ft)
- D is the horizontal distance (ft)
To calculate the fall per foot, divide the total fall by the total distance.
What is Fall Per Foot?
Fall per foot is a measure of the slope or gradient of a surface, typically used in construction and landscaping. It represents the amount of vertical drop (fall) per unit of horizontal distance (foot). This measurement is crucial for ensuring proper drainage and preventing water accumulation on surfaces such as roofs, driveways, and walkways. By calculating the fall per foot, builders and designers can ensure that surfaces are constructed with the appropriate slope to facilitate water runoff and avoid potential damage or safety hazards.
How to Calculate Fall Per Foot?
The following steps outline how to calculate the Fall Per Foot.
- First, determine the total fall (T) in feet.
- Next, determine the horizontal distance (D) in feet.
- Finally, calculate the fall per foot using the formula F = T / D.
- After inserting the values 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.
Total fall (T) = 10 ft
Total distance (D) = 50 ft
