Published limit
Level ground · 90% uniformity
Rivulis T-Tape US data sheet. The table specifies level ground and 90% uniformity. It gives 8 psi as the flow rating and leaves the run-length test inlet pressure unspecified.
What to check for this reel
This tape and 508-12-340 share the same listed line flow at 8 psi. The 8-inch model puts about 150 outlets in 100 ft compared with about 100 for the 12-inch model.
Example zone demand
10 rows of 100 ft each would need about 3.40 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.
