Spraying Liquids with a Density other than Water

Since all tabulations we have computed are based on spraying water, which weighs 8.34 lbs per USA gallon (1 kilogram per liter) conversion factors must be used when spraying liquids that are heavier or lighter than water. To determine the proper size nozzle for the liquid to be sprayed, first multiply the desired GPM or GPA of liquid by the water rate conversion factor. Then use the new converted GPM or GPA rate to select the proper size nozzle.

Example:
Desired application rate is 20 GPA of 28% N. Determine the correct nozzle size as follows:

GPA (liquid other than water) x Conversion Factor
     = GPA

20 GPA (28%) x 1.13
     = 22.6 GPA (water)

The applicator should choose a nozzle size that will supply 22.6 GPA of water at the desired pressure.

Miscellaneous Conversion Factors

One Acre  =  43,560 Square Feet
                =  43.56 1000FT² Blocks
                =  0.405 Hectare

One Hectare  =  2.471 Acres

One Gallon per Acre  =  2.9 Fluid Ounces per 1000FT²
                                 =  9.35 Liters per Hectare

One Gallon per 10000FT²  = 43.56 GPA

One Mile  =  5,280 Feet
               =  1,610 Meters
               =  1.61 Kilometers

One Gallon  =  128 Fluid Ounces
                   =  8 Pints
                   =  4 Quarts
                   =  3.79 Liters
                   =  0.83 Imperial Gallon

One Pound per Square Inch  =  0.069 bar
                                              = 6.896 Kilopascals

One Mile per Hour  =  1.609 Kilometers per Hour
