What to check for this reel

The green emitter lists 0.43 GPM per 100 ft at 10 psi in this spacing. With the same reel length and spacing, the pink-emitter P1-50825-08F-1000 lists 0.60.

Example zone demand

10 rows of 100 ft each would need about 3.80 GPM at the listed 8 psi. Check the flow available under pressure and the manufacturer’s run-length chart for your longest row and slope.
