Flume Lab - Hydraulic Jump

On Tuesday, we derived the Energy Equation for simple 1D flows in a rectangular channel. Today we derived the momentum equation of the same situation. In lab, we will verify the conservation of energy and momentum for a hydraulic jump we produce with a sluice gate in the flume.

Experiment 1

Dr. Gilberto Uroz from the Department of Civil & Environmental Engineering has been kind enough to allow us to use the teaching flume facility. We will be running several sets of experiments. The first experiment will demonstrate the application of the energy and momentum equations to a hydraulic jump produced by a sluice gate. We will follow this lab procedure, which is used in one of Dr. Uroz's undergraduate Hydraulics Course (CEE 3030). You can work together on the lab and make sure you fill out the table before you finish for the 10 different tests. Please work up the Data Anlaysis for problems 1, 2, 3, 4 and 6.

What to Hand In

Please hand in a lab report as per Dr. Uroz's instructions to me at the beginning of class next Thursday. You may work together on the calculations... be forewarned that the form of equations in his instructions may differ slightly from what we will cover in class. Don't panic, figure out how they are they are similar, and work through the calculations. 

Other Experiments

Example of Inducing Hydraulic Jumps with a Wier and Stop Blocks

After, you collect the necessary data for the sluice gate experiments, we will then run a series of qualitative experiments where we play with different flume configurations to help give you an intuitive field for how changes in flow rate (Q), slope (S), and channel geometry (with width constrictions and bed structures like weirs)  alter hydraulics. Please come prepared to make observations.
