Use this form to calculate the irrigation time to apply one inch of water with a center pivot. Find the irrigated area underneath the center pivot by using the pivot acreage calculator. Learn more about the units used on this page.
The Equation
This calculator uses this formula to determine the 1" application time
Where:
= Time it takes to complete a cycle while applying 1" (hrs)
= Irrigated Area (acres)
= Flow rate at the pivot (gpm)
= Percent of full circle being irrigated (as a decimal)
= Irrigation efficiency (as a decimal)
