A field was supplied water from an irrigated
tank at a rate of 120 l/sec to irrigate an area
of 2.5 hect. The duration of irrigation is 8
hours. It was found that the actual delivery at
the field which is about 4 km from the tank
was 100 l/sec. the runoff loss in the field was
estimated as 800 m3. The application eff. In
this situation is?

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.
