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

At 8 psi this model needs 0.45 GPM per 100 ft. With 6-inch spacing, a 100-ft row has about 200 outlets. Measure the wetted pattern in a representative bed before deciding on line spacing.

Example zone demand

10 rows of 100 ft each would need about 4.50 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.
