Question

A wide-channel fl ow undergoes a hydraulic jump from 40
to 140 cm. Estimate (a) V1, (b) V2, (c) the critical depth, in
cm, and (d ) the percentage of dissipation.

Expert Solution
Step 1

Since we only solve up to three subparts, we will solve the first three. Please resubmit the question and specify the other subparts you would like answered.

(a)

Write the relation between the hydraulic jump ratio and the Froude number.

Mechanical Engineering homework question answer, step 1, image 1

Here, Fr1 is the Froude number for initial hydraulic depth, y2 is the final hydraulic depth and y1 is the initial hydraulic depth.

According to the problem, the flow undergoes a hydraulic jump from 40 cm to 140 cm.
