What to check for this reel

For the 12-inch pink-emitter tape, use the published 0.40 GPM per 100 ft at 10 psi in this table. The nominal per-emitter figure and the line-flow table are rounded separately.

Example zone demand

10 rows of 100 ft each would need about 3.60 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.
