IRRIG8 does not store your data or keep any records. Leaving or refreshing this page will delete all your data, so print reports and export the data or graphs if you want to save them.

Beta version: See disclaimer at foot of page

🚿 Linear Move Irrigation Evaluation Calculator v1.0.2

Supporting the Irrigation System Evaluation Code of Practice

Professional Analysis with Enhanced Security & Reporting

🏡 Farm & Property Information
👨‍🔬 Consultant & Evaluation Details
🚜 Linear Move Equipment Information
Length of the linear move lateral
Distance end gun extends beyond lateral (leave blank if no end gun)
Machine length + end gun wetted distance
Length of field that linear move will travel
Effective length × field length ÷ 10,000
Diameter of individual sprinkler wetted pattern
Desired irrigation application depth
🌱 Soil Information
Basic infiltration rate of soil
⚡ Linear Move Speed Testing
Distance measured for speed test (usually 15-30m)
Time taken to travel test distance
Speed = Distance ÷ (Time ÷ 60)
Time to travel across entire field length
📊 System Pressure & Flow Analysis
Pressure at pump discharge
Manufacturer's specified operating pressure
Pressure at the end of the lateral
Actual measured flow rate
Manufacturer's specified flow rate
Will calculate automatically
⚡ Energy Consumption & Operating Costs
Rated power of main irrigation pump motor
Actual power consumption during operation
Cost per kilowatt-hour of electricity
Estimated annual irrigation hours
Cost per cubic metre of irrigation water
Will calculate automatically
💧 Collector Test Setup Along Lateral
Enter a custom number between 10 and 200
Diameter of catch can opening
Duration of uniformity test
Distance from end of lateral to first collector
Distance from end of lateral to last collector
🌡️ Evaporation Control (Section 5.2.2)
Volume added to control collector before test
Volume remaining in control collector after test
Diameter of control collector opening
When water application to collectors began
When measurement of collectors was completed
Will calculate from control collector data
