To determine the nozzle flow rate:
Time the seconds necessary to fill a pint container from a nozzle. Divide the number of seconds into 7.5.
gallons/minute/nozzle = 7.5 7.5 =3 gal./minute
seconds 2.5 sec.

To determine the acreage sprayed per hour:
acres sprayed/hour = boom width (ft.) x MPH x 5280 ft. 24 ft.x5MPHx5280 =14.5 acres
43,560 ft. 2 43,560

Sprayer Tank Capacity*
1. Cylindrical Tanks:
2
gallons = length x diameter x 0.0034 240x72x0.0034 =58.7 gallons
2. Elliptical Tanks:
gallons = length x short diameter x long diameter x 0.0034 240x24x36x0.0034 =705 gallons
3. Rectangular Tanks:
gallons = length x width x depth x 0.004329 240x36x48x0.004329 =1795 gallons
