## What is Sprinkler Pipe Size?

The size of the sprinkler pipe refers to the inner diameter of the pipe, and it is an important factor to consider when designing a sprinkler system. The size of the pipe determines the amount of water that can flow through it, and a larger diameter pipe can handle more water than a smaller one.

## Sprinkler Pipe Size Calculation Formula

To calculate the size of the sprinkler pipe you need, you will need to consider the following factors:

**The total flow rate of your sprinkler system:**This is the amount of water that your sprinkler system will need to deliver per minute. You can calculate this by adding up the flow rate of each sprinkler head in your system.**The pressure loss of your sprinkler system:**This is the amount of pressure that is lost as water flows through the pipes and sprinkler heads. The longer and smaller the pipes, the more pressure is lost.**The length of your sprinkler pipes:**The longer the pipes, the more pressure is lost as the water flows through them.

To calculate the size of the sprinkler pipe you need, you can use the following formula:

**Pipe size (in inches)** = (flow rate (gpm) x pressure loss (psi/100 feet)) / (3.14 x pipe length (feet))
