Irrigation Engineering The peak of a 4 hour flood hydrograph is 240 m3/sec . If the rainfall excess is 80 mm and base flow which is constant is 40 m3/sec, then the peak of 4-hours unit hydrograph will be 30 m3/sec 35 m3/sec 20 m3/sec 25 m3/sec 30 m3/sec 35 m3/sec 20 m3/sec 25 m3/sec ANSWER DOWNLOAD EXAMIANS APP

Irrigation Engineering According to Kennedy, the critical velocity (V₀) in meters in a channel is the mean velocity which keeps the channel free from silting or scouring. Its value is given by (where m is critical velocity ratio and D is the depth of the channel). V₀ = 0.84 mD0.54 V₀ = 0.84 mD0.64 V₀ = 0.55 mD0.64 V₀ = 0.55 mD0.54 V₀ = 0.84 mD0.54 V₀ = 0.84 mD0.64 V₀ = 0.55 mD0.64 V₀ = 0.55 mD0.54 ANSWER DOWNLOAD EXAMIANS APP
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 D = Δ (8.64 D/B) B = Δ (8.64 B/D) D = (8.6 Δ/B) Δ = (8.6 B/D) D = Δ (8.64 D/B) B = Δ (8.64 B/D) D = (8.6 Δ/B) Δ = (8.6 B/D) ANSWER DOWNLOAD EXAMIANS APP
