Introduction
It is key to know the true flow rate from our pump for our understanding of how our experimental model can be related to a true application of an inlet manifold in an AguaClara plant. In order to evaluate the flow rate inside our manifold, the experimental set up was modified so that the Acoustic Doppler Velocimeter (ADV) could be utilized. Two pumping models were evaluated, one where the pump was directly attached to the manifold and the other where it was not connected to the manifold.
Set up
The pump was positioned at the end of the 10-ft long PVC pipe. The ADV was positioned 17 inches away from the end of the pump. Figure 1 shows the ADV positioning. Figure 2 shows the first pump set up (connected). Figure 3 shows the second pump set up. The 10-ft PVC was used so that the flow would be fully developed at the point at which measurements were taken.

Procedure
The procedure is identical for the two experimental models. The ADV was positioned at the top of the pipe. A 30 second velocity measurement was taken here. The ADV was then repositioned to be 1 cm lower than the previous location, and a 30 second velocity measurement was taken. The procedure was repeated until we got to the bottom of the pump.
