Use this form to calculate the water application depth for a traveling big gun sprinkler based on the sprinkler flow rate, travel speed, and travel lane spacing. Learn more about the units used on this page.


Sprinkler Flow Rate:
Irrigation Efficiency:
Travel Lanes Width (distance between sets):
Travel Speed:
Net Water Application Depth:



The Equation

This calculator uses this formula to determine the Net Water Application Rate of a traveling big gun sprinkler.

= Net Water Application (in)

= Flow Rate from the sprinkler(gpm)

= Irrigation Efficiency (as a decimal, or %/100)

= Travel Speed of the Big Gun Sprinkler (ft/min)

= Travel lanes width (ft)
