The nozzle types discussed are the standard (APE), low pressure drift reduction (ADI), and wide pressure range (AXI). The results of this study show that the orifice coefficient (k) of the ADI nozzle with a preorifice was lower than those of the API and AXI nozzles. The ball check strainers had a limiting effect on the nozzle’s flow rate. The pressure exponent coefficients (n) were for the API nozzle and for the ADI and AXI nozzles used with ball check strainers. The n coefficient ranged from to for the API and AXI nozzles and from to for the ADI nozzle, used with typical strainers and without a strainer. The flow rate deviations of APE, ADI, and AXI nozzles used with a ball check strainer were determined as –, –, and –, respectively. The lowest Cd means were found in all nozzle types with ball check strainers, and the means were determined as , , and for the ADI, AXI, and API nozzles, respectively. The Cd means of the nozzles with typical strainers, which is the same as usage without a strainer, were between and for the ADI nozzle, and for the AXI nozzle, and and for the API nozzle. Knowledge of the discharge coefficient of the nozzles used with various strainer types provided a .
