🏡 Farm & Property Information
👨‍🔬 Consultant & Evaluation Details
🚚 Travelling Irrigator Equipment Information
Select the type of travelling irrigation machine
Type of water distribution mechanism
Travel path length (Lt) - distance machine moves
Strip spacing (E) - distance between adjacent strips
Number of parallel irrigation lanes in the field
Strip length × strip width ÷ 10,000
Strip length × strip width × lanes per field ÷ 10,000
Distance from sprinkler to edge of wetted pattern (rw)
Percentage overlap between adjacent irrigation strips
🌱 Soil Information
Basic infiltration rate of soil
Desired irrigation application depth per pass
🔍 Test Design - Number of Transect Lines
Perpendicular lines to delivery tube/cable for uniformity testing

Individual speed tests for each transect allow for more accurate analysis when machine speed varies across the field due to terrain, soil conditions, or operational factors.

Workflow: Select the number of transect lines above, then individual speed test sections will be automatically generated below.

🔧 Default Speed Test (applies to all transects if individual tests not completed)
Distance measured for speed test (usually 15-30m)
minutes seconds
Enter minutes and seconds separately
Speed = Distance ÷ (Time ÷ 60)
🔍 Individual Transect Speed Tests
Select number of transect lines above to generate individual speed test sections
📊 Speed Test Summary
Time to travel across entire strip length (using average speed)
Time to complete all lanes in the field
Average of all transect speeds
📊 System Pressure & Flow Analysis
Pressure at pump discharge
Pressure at inlet to machine (Pi)
Pressure at inlet to gun or distribution system (Ps)
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
💧 Transverse Uniformity Test Setup (Section 4.5.13.4)

Number of Transect Lines: Not set - please go to Speed Test tab first

The number of transect lines is set in the Speed Test tab. If you need to change it, return to the Speed Test tab.

📐 Collector Setup Method (Section 4.5.13.5)
Choose calculation method for collector placement
Diameter of catch can opening
Total duration of transverse uniformity test
🌡️ 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

📄 Upload Transect Data from CSV

Upload a CSV file with transect collector data. Format:

  • 4 columns: Transect Line, Distance from Centre (m), Volume (mL), Collection Time (minutes)
CSV files with or without headers are supported. Custom collector counts will be auto-detected.
Select number of transect lines in the Speed Test tab and collectors per line above to generate input fields
