John and Phil,

 

To follow-up on addressing water distribution in the RaMPs that we discussed last Friday, I have measured the droplet patterns for the 2 nozzles we use and plotted them in the following diagram. The map is approximately to scale. The blue dots (6 inches diameter) represent the location on the ground where a droplet stream falls. Each standard nozzle (light blue) has 24 streams while the center nozzle (dark blue) has 2 – 33 stream outputs). As you see, the portions of the subplots nearest the center receive significantly more water than the outer corners. Please note that this distribution pattern assumes no wind and zero canopy height. I will send this to the design engineers at Senninger to get their recommendations to get more even distribution in the subplots.
