In the realm of construction and architecture, ensuring proper drainage is essential to maintaining the integrity of a structure. One critical aspect is determining the appropriate size for roof drain pipes, facilitating the efficient removal of rainwater. This calculator simplifies the process of determining the ideal diameter for roof drain pipes. By inputting the roof rainwater flow (in cfs) and the drainage time (in minutes), the calculator swiftly computes the necessary drain pipe diameter (in inches).
Formula of Roof Drain Pipe Size Calculator
The formula used within the Roof Drain Pipe Size Calculator is as follows:
D = sqrt(Q × 4T / π)
Where:
- D represents the drain pipe diameter (in inches).
- Q denotes the roof rainwater flow (in cfs).
- T signifies the drainage time (in minutes).
General Terms Table:
| Term | Description |
|---|---|
| Roof Rainwater Flow (cfs) | The volume of rainwater running off a roof within one second, often measured in cubic feet per second (cfs). |
| Drainage Time (minutes) | The duration required for water to drain from the roof, measured in minutes. |
| Drain Pipe Diameter (inches) | The width of the pipe required for efficient rainwater drainage, measured in inches. |
Example of Roof Drain Pipe Size Calculator
Suppose a roof receives a rainwater flow of 6 cubic feet per second (cfs) and has a drainage time of 10 minutes. Plugging these values into the Drain Pipe Size Calculator yields a drain pipe diameter of approximately 4.13 inches.
