Question
The pre-jump Froude Number for a particular flow in a horizontal rectangular channel is 10. The ratio of sequent depths (i.e., post-jump depth to pre-jump depth) is ________
Correct answer
13.6 to 13.7
Solution
For a hydraulic jump in a horizontal rectangular channel, the ratio of sequent depths (post-jump) and (pre-jump) is given by the Belanger equation:Given the pre-jump Froude Number :Rounding to two decimal places, the ratio of sequent depths is approximately 13.65, which falls within the specified range of 13.6 to 13.7.
