List of top Irrigation and Drainage Engineering Questions on Methods of Irrigation

In a field test of a drip irrigation system: 
Min = 45 L/h, Max = 65 L/h, Avg = 50 L/h. 
Application efficiency = 90%. 
Emitter coefficient of variation = 0.07. 
One emitter per plant. 

Find the drip irrigation efficiency (round off to 2 decimals).
