2-13. ESTABLISHING APPLICATION PARAMETERS.
a.
Introduction. Before attempting to spray any material, application parameters must be established. Coverage
gallons per square yard and spraybar width should already have been determined. Use the procedure below, and Figure
2-1, to understand how to determine tow vehicle travel speed, gallons per minute, and spraybar height.
b.
Tow Vehicle Travel Speed and Gallons per Minute Calculations.
NOTE
Application charts are Figure 2-2, sheets 10 and 11. Follow the procedure below
using the example given to understand how to establish the application
parameters, then refer to Application Charts.
Figure 2-1. Application Chart - Example.
(1)
Refer to Figure 2-1, and select the Rate of Coverage (Gallons per Square Yard) desired from the first
column (1).
(2)
Select the desired width of spraybar from bottom row (2).
(3)
Move to the right from Gallons Per Square Yard, and up from Spraybar Length In Feet. At the point of
intersection you will find the travel speed in FPM (Feet per Minute).
(4)
From FPM figure, move directly up to Gallons Per Minute Pump Tachometer (Flow Rate Indicator) to find
gallons per minute.
(5)
Refer to Figure 2-1 and follow the example below:
(a)
In example Figure 2-1, rate of coverage desired is 1.0 gallons per square yard (4).
(b)
Spraybar width desired is 12 feet (5).
(c)
Travel speed will be 105 ft per minute (6).
(d)
Pump tachometer (Flow Rate Indicator) will read 140 gallons per minute (7).
