General Information 69
NOTE: The MOST common problem is failure
to select the correct nozzle size and failure to
perform the “Initial Set-Up” procedure!!
Since all nozzle charts or tabulations are based
on spraying water, which weighs 8.34 LBS per
USA gallon, conversion factors must be used
when spraying solutions which are heavier or
lighter than water. Using conversion factors from
the tables below, multiply by the catalog tabula-
tor GPM and GPA rates - to arrive at the value
for the solution to be sprayed.

7.0 Ibs. per gallon .84 1.09
8.0 Ibs. per gallon .96 1.02
8.34 Ibs. per gallon 1.00 1.00
9.0 Ibs. per gallon 1.08 .96
10.0 Ibs. per gallon 1.20 .91
11.0 Ibs. per gallon 1.32 .87
12.0 Ibs. per gallon 1.44 .83
14.0 Ibs. per gallon 1.68 .77
16.0 Ibs. per gallon 1.92 .72
18.0 Ibs. per gallon 2.16 .68
20.0 Ibs. per gallon 2.40 .65
To calculate gallons per minute, use this formula:
Gal. Per Acre x MPH x Width (in feet)
= Gal. Per Minute
495
Divide the calculated GPM, by the conversion
factor, to find the actual nozzle size required.
EXAMPLE: Using the previous example, the
required size was .35 GPM. Assume you want
to spray a fertilizer that weighs 10.0 LBS per
gallon. As expected, a lower amount of this
thicker, heavier material would go through a
nozzle if the same pressure is used. To com-
pensate, use the conversion factor in the
table.
.35
= .38 GPM is the actual GPM required
.91
Again, refer to nozzle charts or tables to find
the nozzle that is closest to .38 GPM at a given
pressure. Use that SIZE and that PRESSURE.
NOTE: If this correction factor was not in-
cluded, an additional error of 9% would be
introduced.
BAND SPRAYING
The two key points for calibrating the 8160 for
band spraying is: 1) the gallons per acre (Broad
-
cast Rate) and 2) the total width of the actual
ground being sprayed (sum of the individual
band widths).
When band spraying, program the boom width to
the total inches of each of the width of the bank
per boom. For example, 4 rows with 15 inch
wide bands would equal 60 inches. Suppose the
chemical you are spraying has a recommended
rate of say, 10 gallons per acre (Broadcast rate).
No conversions are required; simply program
your target RATE 1 or RATE 2 to 10 gallons per
acre.
To recalculate the total ACRES, as might be the
case if you used the 8160 for Band spraying and
would like to know the total acres of the whole
field, use the ratio procedure shown below.
Example:
Old Acres Sprayed - 300 inches
Old total boom width - 120 inches
New total boom width - 240 inches
1
Old Acres Sprayer (300)
=
New Recalculated Acres
Old Boom Width (120) 240 New Boom Width
2 New Recalculated Acres =
Old Acres Sprayed x New Boom Width
Old Boom Width
3 New Recalculated Acres = 600 =
300 x 240
