Abstract:

This work investigated the applicability of using hot-wire instrumentation for the measurement of the droplet size distributions of insecticide and herbicide sprays. Under Phase I, mineral oil was used as a model liquid. Tests were performed to determine the effects of eccentric collisions, longitudinal variations along the wire, probe contamination, and temperature stability. A calibration curve was obtained for mineral oil which is different than that of water. This calibration curve shows that the hot-wire approach is accurate for a size range of 1 to 240 micrometers. This range is more than adequate for existing insecticide spray apparatus. Tests using actual insecticides have shown that the calibration curve obtained for mineral oil may be used for at least the two insecticides investigated.
