What this tool does
Totals emitters without allowing direct and geometry input to be counted at once.
When to use it
Use with the actual emitter discharge at operating pressure and field row geometry.
Inputs and supported units
Each labelled field explains the quantity it expects. Unit-system changes convert existing numeric entries once and keep calculations on a single SI internal basis. Supported shared units include L/min and GPM, metres and feet, kPa and psi, millimetres and inches, kW and hp, and °C and °F as relevant.
Calculation or decision method
How to interpret the result
Read the primary result with the supporting breakdown and warning. A plausible number is not evidence that every input, operating case or design constraint has been included.
Worked example
100 m rows at 0.5 m spacing, 10 rows and 2 L/h emitters total 4,020 L/h.
Assumptions
Entered measurements represent the same operating condition. Calculations use unrounded SI values and convert only for display.
Limitations
This is a preliminary planning screen, not a design approval, irrigation audit, pump curve analysis or distribution-uniformity test.
