In a rectangular channel, the ratio of the velocity head to the flow depth for critical flow condition is
In a rectangular open channel, 2.0 m wide, water flows at a depth of 0.8 m. It discharges over an aerated sharp-crested weir over the full width, with depth over weir crest being 0.25 m. Cc.= 0.61. Adjusting for velocity head of approach, what would be the discharge through the channel? √2g = 4.43 units
Hydraulically, the economical section of drains for large flow is:
Discharge over Cipolletti weir of length 200 cm for a head over the weir of 100 cm in m3/s is:
Consider the following statements with respect to weir under discussion:1. Its design corresponds to soft sandy foundation.2. The difference in weir crest and downstream river bed may not exceed3. When water passes over it, the longitudinal location of the formation of a hydraulic jump is variable.This weir is of the type
In a 90° triangular notch, in the error in the estimated discharge for a given head due to an error of 1% in cutting the vertex angle is
At a hydraulic jump, the depths at its two sides are 0.3 m and 1.2 m. The head loss in the jump is
In a rectangular channel, carrying a certain discharge at a depth Y0 and Froude number \(F_{0'}\:then\:\dfrac{Y_c}{Y_0}=\)
For best hydraulic rectangular cross - section of an open channel, its depth should be equal to
A hydraulic jump takes place in a frictionless rectangular channel. The pre-jump depth is yp. The alternate and sequent depths corresponding to yp are ya and ys respectively. The correct relationship among yp, ya and ys is:
