Abstract
In order to characterize the water spray from a standard orifice,pendent spray sprinkler, measurements were made using an optical array probe droplet analyzer. the water droplet sizes and speeds from the sprinkler were measured at various locations in the spray field. the study resulted in mean droplet speeds, droplet size distributions, and median droplet sizes based on both the number and volume of the measured drops.
