System Pumping Requirements
Use this form to calculate the system capacity (flow rate) required to meet the demands of a field.
This calculator uses this formula to determine the system pumping requirements of a field.
= Total flow rate required to operate irrigation system (gpm)
= The net application required per week (in)
= Total area to be irrigated (acres)
= Total hours available to operate per day (hrs)
= Total days available to operate each week (days)
= Efficiency of the irrigation system (as a deciaml)
