agri.irrigation Calculator
Calculates daily and monthly irrigation water volumes and the pump flow rate needed to deliver them across a field, based on crop evapotranspiration and system efficiency. Helps farmers size pumps, pipes, and storage tanks correctly.
Inputs
Area Ha
Two-dimensional surface extent (m²). For complex shapes, break into simpler sub-shapes and sum.
Etc Mm Day
Reference formula or conversion factor shown for context.
Efficiency
Useful output divided by total input, as a percentage. 100% is impossible due to losses (heat, friction, resistance).
Runtime
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Results
daily water need (m^3)
The value at the specified point or condition.
monthly water (m^3)
The value at the specified point or condition.
required flow rate (L/s)
The value at the specified point or condition.
gross irrigation depth (mm)
The computed depth.
efficiency
Useful output divided by total input, as a percentage. True 100% efficiency is impossible — losses appear as heat. LEDs: 30–50%. Electric motors: 85–97%. Switching supplies: 85–95%.
