Formula and method
Session volume (L) = heads × flow per head × runtime. Weekly volume = session volume × sessions.
All head flows are added for the selected runtime, then extended to weekly and approximate monthly use.
Worked example
Twenty 15 L/min heads running 30 minutes use 9,000 L per session and 27,000 L over three weekly sessions.
Understanding the result
Treat the calculated values as a planning estimate. Compare them with your field records, product information, local conditions and operational capacity before acting.
Important: Results depend on the accuracy of your inputs and the assumptions shown. Local soil, weather, crop, animal and market conditions can change the appropriate decision.
