In order to achieve turbulent flow in our flocculator setup, we needed to figure out if our pumps can handle very high flow rates to get high Reynolds number. For turbulent flow, our target Reynolds number is 2500, with flocculator inner diameter of 0.6cm. The calculation shows that the flow rate needs to be at least 11.8 mL/s for turbulent flow. With our current setup, the max flow rate is 3.1 mL/s. Thus, one of our solutions was to add more pump heads, since the max flow rate of pump is limited by how fast a pump head motor can rotate. In process controller, we added in new set points - "3-Alum Number of Heads" and "3-Clay Number of Heads" -
