# Sprinkler Run Time Calculator

## What is Sprinkler Run Time?

Sprinkler run time refers to the amount of time that a sprinkler system is turned on and water is applied to the landscape. Calculating sprinkler run time is important because it helps to determine the amount of water that is needed to adequately irrigate an area, and it can help to identify any potential problems with the irrigation system.

## Sprinkler Run Time Calculation Formula

To calculate sprinkler run time, you will need to know the following information:

- The flow rate of the sprinkler system, which is typically
**measured in gallons per minute**(gpm). - The area that the sprinkler system is covering, which is typically
**measured in square feet**. - The amount of water that the landscape needs, which is typically
**measured in inches**. This can be determined by considering factors such as the type of plants being irrigated, the soil type, and the local climate.

To calculate sprinkler run time, use the following formula:

**Run time (minutes)** = (Water needed (inches) * Area (square feet)) / (Flow rate (gpm) * 0.623)

For example, if you have a sprinkler system with a flow rate of 10 gpm, and you need to apply 1 inch of water to a lawn that is 1000 square feet, the run time would be:

**Run time (minutes)** = (1 inch * 1000 square feet) / (10 gpm * 0.623) = 16 minutes
