Fall 2022 Exercise Set 2

LAST NAME, FIRST NAME

R00000000

Purpose :¶

Apply principles of specific energy in rectangular open channels; apply definition of choked flow

Assessment Criteria :¶

Completion, results plausible, format correct, calculations (Jupyter Notebook) are shown.

Problem 1¶

Water is flowing at a depth of 10 $ft$ with a velocity of 10 $\frac{ft}{sec}$ in a rectangular channel. A smooth upward step in the channel bottom of 1 $ft$ is proposed

Determine:

The flow depth (on the step).
The change in water surface elevation.
The maximum allowable step height that prevents choking (assume a head loss coefficient of 0).

Problem 2¶

Water is flowing at a depth of 10 $ft$ with a velocity of 10 $\frac{ft}{sec}$ in a rectangular channel. A smooth contraction in width from 10 $ft$ to 9 $ft$ on a horizontal bottom is proposed
