Irrigation EngineeringIrrigation Engineering and HydrologyHARD
Choose the correct answer
A
Delta=DB/864
B
Delta=8.64B/D
C
D=Delta/(8.64B)
D
B=8.64D/Delta
Correct Answer
B. Delta=8.64B/D
Why is this the answer?
Using 1 cumec-day over 1 hectare = 8.64 cm gives Delta = 8.64B/D in metres when D is ha/cumec.
