A field was supplied water from an irrigated tank at a rate of 120 l/s...
Introduction
To determine the application efficiency of irrigation in this scenario, we need to analyze the data provided regarding water supply, actual delivery, and losses.
Data Summary
- Water Supply Rate: 120 l/sec
- Irrigation Area: 2.5 hectares
- Duration of Irrigation: 8 hours
- Actual Delivery Rate: 100 l/sec
- Runoff Loss: 800 m³
Calculating Total Water Supplied
- Total Supply (in liters):
120 l/sec * 8 hours * 3600 sec/hour = 3,456,000 liters
- Total Supply (in m³):
3,456,000 liters = 3,456 m³
Calculating Total Water Delivered
- Total Delivery (in liters):
100 l/sec * 8 hours * 3600 sec/hour = 288,000 liters
- Total Delivery (in m³):
288,000 liters = 288 m³
Calculating Water Used for Irrigation
- Water Used for Irrigation (in m³):
Total Delivery - Runoff Loss
288 m³ - 800 m³ = -512 m³ (indicating excess runoff)
Application Efficiency Calculation
- Application Efficiency (AE):
AE = (Water Used for Irrigation / Total Water Supplied) * 100
AE = (288 m³ / 3,456 m³) * 100 = 8.34%
Conclusion
The application efficiency of the irrigation system is approximately 8.34%, indicating a significant loss of water, primarily due to runoff. This suggests a need for improved irrigation methods to minimize water wastage and enhance efficiency.
