Time to Run Irrigation

Use water depth wey you choose and emitter flow find how long irrigation need run.

Your numbers

Time wey irrigation need run

—

Assume total emitter flow and application efficiency wey you enter remain constant. Na you choose water-depth target; crop needs, soil behavior and weather no dey assessed.

Formula

Use V = Ad/e and t = V/q. A na area for m², d na di water depth wey you choose for mm, e na application efficiency as fraction, and q na total emitter flow for L/min. V na litres and t na minutes.

Use water depth wey you choose and emitter flow find how long irrigation need run.

Example wey show the calculation

Area wey need covering (m²): 20
Water depth wey you choose (mm): 10
Flow from all emitters together (L/min): 20
Efficiency of water application (%): 80

Time wey irrigation need run: 12.5 minutes
Water volume wey supply must provide: 250 L

Where e fit work and limits

Assume total emitter flow and application efficiency wey you enter remain constant. Na you choose water-depth target; crop needs, soil behavior and weather no dey assessed.

We check inputs for missing values and allowed ranges. Result wey pass the finite numeric range no go show. Rounding affect wetin display, while calculation use the model numeric precision.

Check your units and assumptions before you rely on result. Changing label no convert currency or physical unit.
