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 = 0.55 mD0.54 V₀ = 0.55 mD0.64 V₀ = 0.84 mD0.64 V₀ = 0.84 mD0.54 V₀ = 0.55 mD0.54 V₀ = 0.55 mD0.64 V₀ = 0.84 mD0.64 ANSWER DOWNLOAD EXAMIANS APP
Irrigation Engineering The rainfall on five successive days were measured as 100 mm, 80 mm, 60 mm, 40 mm and 20 mm respectively. If the infiltration index or the storm loss rate for the catchment area is earlier estimated as 50 mm/day, the total surface run off will be 140 mm 90 mm 50 mm 60 mm 140 mm 90 mm 50 mm 60 mm ANSWER DOWNLOAD EXAMIANS APP
