The 1.5 cm wide rectangular channel in the laboratory was used to create a hydraulic jump; the following data were collected: y1 = 1.25 ± 0.05 cm; y2 = 5.6 ± 0.1 cm; Q = 8 liters/30 sec Assume the water temperature was 20°C. (Note the mixed units above – please present your solutions in si units)

(a) Use the theoretical equation to predict the conjugate depth ratio, y2/y1, based on the initial depth, y1. Compare the value to the lab-derived ratio (lab y2/lab y1).

Discuss the results. (b) Calculate critical depth (in cm). Verify if flow transitioned from supercritical to subcritical.

(c) Calculate the total energy at points 1 and 2. How much energy was lost in the jump? What percentage of the upstream energy was lost in the jump?

A long rectangular concrete channel (b = 10 ft, n = 0.015) carries 400 cfs. There is a grade break in the channel; the slope upstream of the grade break is 0.02 and the slope downstream of the grade break is 0.002. The following equations are valid for a rectangular channel: • DC = [(Q2)/(g*b2)]1/3 • y2 = 0.5*y1*[(1+8NFr12)1/2 -1] (for hydraulic jump) • NFr = v/(g*y)1/2 a) Use calculations to classify each section of the channel (steep, mild, horizontal,...
