Experiment 2: 10' Manifold with Am/Ap = 1

Results

The results of our second experiment seem to reaffirm the results that we found in the first experiment, despite the problems with data collection that existed in the first experiment. The flow starts low then peaks in the first quarter of our manifold and then gradually decreases after that.

The good news with these results is that we feel like the flow is sufficiently uniform, only varying +-0.05 m/s, for it to work in the AguaClara plants. It also achieves the goal of not dropping below the scour velocity of 0.15m/s, so we can be confident that flocs will not settle out in the manifold. We still do not understand the fluid mechanics of what is happening in the manifold and need to investigate that further.
