A hydraulic jump at the base of a spillway of a dam is such that the depth.
upstream and downstream of the jump are 0.7 m and 3.6 m respectively. The
spillway is 50 m wide. Calculate:
5.1.1 The flow rate over the spillway
5.1.2 The head loss across the hydraulic jump
5.1.3 The power dissipated by the hydraulic jump
5.2.1
A trapezoidal channel (figure 5) with a bottom width of 6 m, free surface width
of 12 m, and flow depth of 2.2 m discharges water at a rate of 120 m³/s. If the
surfaces of the channel are lined with asphalt (n 0.016), determine the
elevation drop of the channel per kilometer.
