Drain Capacity Calculator

Drain Capacity Calculator calculator can be used to estimate the capacity of a drain based on pipe diameter and flow rate. This is useful for sizing drains for plumbing, irrigation, and other drainage systems.

Calculation Formula

Drain Capacity (gpm) = Flow Rate (gpm)

Where:
Flow Rate (gpm): Gallons per minute of water flowing through the pipe

How to Use the Drain Capacity Calculator

  1. Enter the pipe diameter in inches. This is the nominal diameter of the drain pipe.
  2. Enter the flow rate in gallons per minute (gpm). This is the amount of water flowing through the pipe per minute.
  3. Click the "Calculate" button to compute the drain capacity.
  4. The calculator will display the drain capacity in gallons per minute (gpm).

Understanding the Results

The drain capacity is the maximum flow rate the drain can handle without causing surges or backups. This value is important for sizing drains for plumbing, irrigation, and other drainage systems.

Example

If you have a drain pipe with a diameter of 4 inches and a flow rate of 100 gallons per minute, the drain capacity will be 100 gpm.
