Irrigation Engineering The scour depth D of a river during flood, may be calculated from the Lacey's equation D = 0.47 (Q/f) D = 0.47 (Q/f)1/2 D = 0.47 (Q/f)1/3 D = 0.47 (Q/f)2/3 D = 0.47 (Q/f) D = 0.47 (Q/f)1/2 D = 0.47 (Q/f)1/3 D = 0.47 (Q/f)2/3 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 = 0.55 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 According to Lacey, depth of scour in a river depends upon the straightness of the reach. If D is the depth of scour in regime flow in a right angled bend, it is 1.50 D 1.75 D 2.00 D 1.25 D 1.50 D 1.75 D 2.00 D 1.25 D ANSWER DOWNLOAD EXAMIANS APP
