An outlet irrigates an area of 20 ha. The discharge (I/s) required at this outlet to meet the evapotranspiration requirement of 20 mm occurring uniformly in 20 days neglecting other field losses is

1. 2.52
2. 2.31
3. 2.01
4. 1.52

Correct Option: B

Volume of water = 20 × 10⁴ × 20 × 10^–3 m³
= 4000 m³

Q =	4000	= 2.31 × 10^–3 m³/s = 2.31 litres/s.
	30 × 24 × 60 × 60
