The experimental model is displayed below. The five gallon stock tank consists of a calcium hypochlorite solution at a concentration of 17.435 g/L. In Honduras, the stock tank consists of a 55 gallon tank that runs for approximately three days. In order to model this, the stock tank was run at 8 hour intervals and refilled when it was depleted, and then run again. The target flow rate used 48.1 mL/min, the same as 55 gallons/ 3 days. Overnight, the flow rate was to be slowed down to approximately a third of the flow rate by decreasing the change in head by a third. It would be evident that the system had reached failure when the flow rate had decreased significantly. Steps would then be taken to determine which portion had failed.
