TERMS USED

GPA = Gallon per Acre
GPM = Gallon per Minute
Ac/Min = Acres/Minutes
Ac/Hr = Acres/Hour
GPM/Noz = Gallon per Minute/Nozzle
Min/Ac = Minute/Acre
Min/Tree = Minute/Tree
MPH = Miles per Hour
Min/Load = Minute/Load
PSI = Pounds per square inch
Trees/Min = Trees/Minute
TS A or B =  Tree Spacing
SW   = Swath Width

ORCHARD APPLICATION FORMULAS:

If you are going to spray both sides of the row go down the middle of the row. Use the Orchard Application Formulas as given.
If you are spraying only one side to the row. Multiply GPA by .5
1. Ac/Mn = MPH X TSB x .00202 or MPH x TSB
                                                                495
2. Ac/Hr = MPH x TSB  x .1212 or MPH x TSB
                                                             8.25
3. GPA = GPM x495 
                MPH x TSB 
4. GPA = 43560 X gallons sprayed per test run 
                            TSB x feet of test run
5. GPM = GPA x MPH x TSB
                         495
6. GPM/Noz = GPA x MPH x TSB
                       # of noz x 495
7. Min/Ac =        495         
                       MPH x TSB  
8. Min/Tree =  .0114 x TSA
                             MPH
9. MPH = Tree/Min x TSA
                         88
10. MPH = Trees passed x TSA x.682
                     Seconds traveled
11. MPH = GPM X 495
                    GPA X TSB
12. MPH = .682 x feet traveled     OR    Distance F x 60
                    seconds traveled                 seconds traveled x 88
13.  Min/Load  = 495 gallons/load  OR Time M for gallons sprayed = 495 x gallons sprayed
                             GPA x TSB  x MPH                                                        GPA x TSB x MPH     
14. PSI =      ((GPA x MPH x TSB)  ÷(495 x # Noz x GPM/Noz at 30 psi))2  x 30
