11. Instrumentation and reporting bias directly affect drop size data. 12. Hollow cone nozzles provide the smallest drop size distributions. 13. The following guidelines are suggested to facilitate understanding and effective use of the drop size data. 14. Rain drop size distribution ( DSD ) is an important consideration for studying rain fade characteristics. 15. Hollow cone nozzles produce the smallest drop size . 16. Select the drop size mean and diameter of interest that is best suited for the application. 17. Success in these applications is often completely dependent on factors such as drop size and spray velocity. 18. A "'disdrometer "'is an instrument used to measure the drop size distribution and velocity of falling hydrometeors. 19. A disdrometer is an instrument used to measure the drop size distribution and velocity of falling hydrometeors. 20. The drop size is the size of the spray drops that make up the nozzle s spray pattern.
