The good news with these results is that the flow from the ports might be sufficiently uniform for it to work in the AguaClara plants. The mean velocity is 0.214 m/s and has a standard deviation of 0.021 m/s, which might be low enough variation for the AguaClara plants. The mean velocity might be a little high when considering the restriction of floc breakup prevention as there is an average energy dissipation rate of 19 mW/kg when the max allowable to maintain flocs is 10 mW/kg. This was determined by using the equation

We estimated the flow rate being provided by the pump to be 3.8 L/s. This value was calculated using the following equation:

This finds the average port flow of the measured ports and then multiplies it by the total number of ports. Given this flow rate, the velocity inside the manifold would be 0.21 m/s at the beginning of the manifold. This meets the specification of
