Answer 1

Question:-

Derive a relationship b/w duty and delta. Using this relationship, find delta for a crop with base period of 100 days. The duty of crop is 432 ha/cumec.

Answer :-

D = duty in hectares/cumec

∆ = total depth of water supplied in metres

B = base period in days

If we take a field of area D hectares, water supplied to the field corresponding to the water depth ∆ metres will be = ∆ x D hectares-metres.

=D×Δ×104 cubic-metres. .... (1)

Again for the same field of D hectares, one cumec of water is required to flow during the entire base period. Hence, water supplied to this field.

=(1)×(B×24×60×60)m3 .... (2)

Equating Equations (1) and (2), we get

D×Δ×104=B×24×60×60

Δ=(B×24×60×60)/(D×104)=8.64B/Detres.
