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)

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

= Travel lanes width (ft)
