A tractor sprayer is fitted with 20 hollow cones nozzles to attain application rate of 200 l/hr. During the calibration test, the nozzle flow rate was found to be 1.25 l/min whereas, the rated nozzle flow rate was found to be 0.473 l/min was available at 275 kPa. If the nozzle produces droplets with volume median diameter 200 m at 1 Mg Pascal, the droplet at the desire flow rate is?

• A. 161 m
• B. 164 m
• C. 167 m
• D. 170 m
