点滴灌漑計算機

点滴灌漑システムの総水量と散水量を算出します。

はじめに

Drip Irrigation Calculator — Total water and application rate for a drip system. Enter Number of emitters, Emitter flow rate (L/hr), Run time (hours), Emitter spacing (m), Row spacing (m) to get an instant, accurate result.

計算式

Total water applied (L) = number of emitters × emitter flow rate (L/hr) × run time (hours). Application rate (mm/hr) = emitter flow rate / (emitter spacing × row spacing), since 1 liter per square meter equals 1 mm of depth. Exact unit-derived formulas.

ステップごとの説明

  1. Enter the Number of emitters.
  2. Enter the Emitter flow rate (L/hr).
  3. Enter the Run time (hours).
  4. Enter the Emitter spacing (m).
  5. Enter the Row spacing (m).
  6. Click Calculate to see your result instantly.

実例

Example: With Number of emitters = 10, Emitter flow rate (L/hr) = 2 L/hr, Run time (hours) = 3, Emitter spacing (m) = 0.5, Row spacing (m) = 1, the Drip Irrigation Calculator gives Total Water Liters: 60, Application Rate Mm Hr: 4.

よくある質問

How is application rate in mm/hr useful?
It lets you compare drip irrigation directly against a crop's daily water requirement (from the evapotranspiration or irrigation requirement calculators) to set an appropriate run time.
Why do emitter spacing and row spacing both matter?
Together they define the ground area each emitter effectively waters, which is needed to convert a volumetric flow rate into a depth-based application rate.
What inputs does the Drip Irrigation Calculator need?
You'll need to provide: Number of emitters, Emitter flow rate (L/hr), Run time (hours), Emitter spacing (m), Row spacing (m). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Drip Irrigation Calculator?
The Drip Irrigation Calculator applies the formula exactly as calculated — Total water applied (L) = number of emitters × emitter flow rate (L/hr) × run time (hours). Application rate (mm/hr) = emitter flow rate / (emitter spacing × row spacing), since 1 liter per square meter equals 1 mm of depth. Exact unit-derived formulas. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Drip Irrigation Calculator free to use?
Yes, the Drip Irrigation Calculator is completely free, requires no signup, and runs instantly in your browser.

点滴灌漑計算機について

The Drip Irrigation Calculator uses a real, verifiable formula — Total water applied (L) = number of emitters × emitter flow rate (L/hr) × run time (hours). Application rate (mm/hr) = emitter flow rate / (emitter spacing × row spacing), since 1 liter per square meter equals 1 mm of depth. Exact unit-derived formulas. — so results are accurate every time, not an approximation.
