Q3. Water flows down a dam spillway and then forms a hydraulic jump. Just before the jump, the velocity of flow is 7.5 m/s, and the water depth is 0.15 m. Determine the average velocity of the flow downstream of the channel after the jump. 75m/s y2 y1=0.15m V2=.... ..m/s

Water flows through a pipe AB 1.2 m diameter at 3 m/s and then passes through a pipe BC 1.5 m diameter. At C, the pipe branches. Branch CD is 0.8 m in diameter and carries one- third of the flow in AB. The flow velocity in branch CE is 2.5 m/s. Find the volume rate of flow in AB, the velocity in BC, the velocity in CD and the diameter of CE.

Prob. # 5 (a): In a partially flowing channel having a isosceles-triangular cross section as shown below (Figure 5a), the rate of flow can be expressed as Q=KAR 2³, where k is a constant and A and R are respectively cross sectional area and the hydraulic radius. Determine the depth at which the discharge is maximum. For the channel, A= [B - (h/√3)]h, and P= B + (4h/3). 60 60° Figure section. 5a-Triangular channel cross

The Aqueduct canal has side slopes at 45° to the horizontal base of the channel and conveys water at a depth of 1.5m. a. Calculate the width of the base.b. Calculate the gradient of the channel bed to discharge 2.54m3/s with a mean velocity of flow of 1.56m/s. Take Chezy C = 66.
