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 mD0.64 V₀ = 0.84 mD0.54 V₀ = 0.55 mD0.64 V₀ = 0.55 mD0.54 V₀ = 0.84 mD0.64 V₀ = 0.84 mD0.54 V₀ = 0.55 mD0.64 V₀ = 0.55 mD0.54 ANSWER DOWNLOAD EXAMIANS APP
