Use this as a planning estimate. Verify product labels, local conditions and supplier packaging before buying or applying materials.

THE FORMULA

How the result is calculated

Zone flow = emitter count × gallons per hour. Weekly gallons = zone flow × runtime hours × runs per week.

SproutScale preserves full precision while calculating and rounds only the displayed result or the final purchasable unit.

FIELD NOTES

Before you act

  • Use emitters with known, matching flow rates.
  • Stay within the tubing and pressure regulator capacity.
  • Check the farthest emitters for even output.
QUICK ANSWERS

Drip irrigation FAQ

Can different emitters share one zone?

They can, but add each flow group separately for accurate totals and verify pressure balance.

Does drip runtime equal sprinkler runtime?

No. Drip applies water to a smaller area at a different rate, so schedule it from emitter output and root-zone needs.
