Coefficient of discharge for orifice flow can be calculated using Reader-Harris/Gallagher (1998) equation (ISO 5167): where is: β - diameter ratio d 1 /d 2 ; Re D - Reynolds number based on bigger diameter; d 1 - internal diameter (smaller); d 2 - internal diameter (larger); Dec 29, 2020 · Discharge rate: gallons per minute (gpm). In order to choose the correct nozzle size, the discharge rate must be calculated, using application rate, ground speed, and swath width. If the sprayer has a single nozzle, swath width is the effective width sprayed. If it has a boom with multiple nozzles, swath width should be the spacing between nozzles. Note: If the nozzle is on the wiper arm, you must first lift the wiper arms off the windshield in order to remove the line. Step 2: Remove the nozzle. Use a medium flat head screwdriver to push in the tabs on the washer nozzle and pop out the nozzle. If the nozzle is retained by a screw, unscrew it first and then the nozzle will come off.

It should be noted that while it is common to characterize nozzle holes with the discharge coefficient, C d, an accurate determination of C d requires knowledge of the nozzle diameter. For some nozzle hole designs, such as those that have a diameter that varies along the length of the hole, it can be difficult to accurately quantify the diameter.

There is a conflict between the nozzles recommended for the 20-29′ spacing range of the chart and my previous advice to “avoid using rotors with nozzle flows that are less than 2.5 GPM”. This is because the Nozzle Selection Guide assumes you will be mixing 20-29′ radius rotors together on the same valve with 30′ plus radius rotors.

A converging nozzle can only become supersonic at the exit stage; the speed increases monotonically along the nozzle. If a converging nozzle is fed from a constant pressure constant temperature chamber, the flow rate grows as the discharge pressure is being reduced, until the flow becomes sonic (choked) and
