Irrigation Engineering If Δ is the depth of water in metres, B is the number of days of base period and D is the duty in hectare/cumec, the relationship which holds good, is B = Δ (8.64 B/D) D = Δ (8.64 D/B) Δ = (8.6 B/D) D = (8.6 Δ/B) B = Δ (8.64 B/D) D = Δ (8.64 D/B) Δ = (8.6 B/D) D = (8.6 Δ/B) ANSWER DOWNLOAD EXAMIANS APP
