  1. Find the appropriate nozzle color on the left side of the table.
  2. Determine the bench length or a specific section length that you intend to irrigate.
  3. The color-coded shaded area will indicate the appropriate hose size.

Feed the hose from the center if you want to reduce the required hose size or the length is longer than recommended. Bench length to use then would be the distance from the feeder connection to the end of the bench.

The tables are calculated on a maximum of +/- 5% flow variation.
It is possible to achieve higher uniformities by either shortening the sprinkler lines or using the next larger pipe size.
