PPT-Spray Droplet Sizing –

Understanding the Basics Brad Fritz USDA ARS Aerial Application Technology Research Unit College Station Texas Droplet Diameter D D droplet diameter V droplet volume At equal volume with droplets of ½ diameter. At 3 bar spray performance is often equivalent to a medium flat fan spray At lower pressures spray drift is reduced by up to 75 so the balance between spray coverage and drift reduction can be easily adjusted by the operator More drops per litre tha Photograph: Tony Clarke, VOCALS .
