To calculate the water requirement of your lawn, you will need to consider the climate, soil type, and grass type. Here’s a general guideline:
For hot and dry climates, the water requirement is usually around 1-2 inches per week.
For cool and humid climates, the water requirement is usually around 0.5-1 inch per week.
For sandy soils, the water requirement is usually around 0.5-1 inch per week.
For clay soils, the water requirement is usually around 1-2 inches per week.
Using the Precipitation Rate and Water Requirement to Calculate Run Time
Once you have calculated the precipitation rate and water requirement, you can use the following formula to calculate the ideal run time:
Run time (minutes) = Water requirement (inches) x 60 / Precipitation rate (inches per hour)
For example, if the water requirement is 1 inch per week, and the precipitation rate is 0.5 inches per hour, the run time would be:
Run time (minutes) = 1 x 60 / 0.5
Run time (minutes) = 120 minutes
This means that the sprinkler zone should be on for 120 minutes to deliver 1 inch of water.
