The flow through the alum doser exit tubing was determined given user-defined parameters for the dimensions of the alum stock tank, such as height of tank (and thus, height of alum level) and diameter of exit orifice (and thus, diameter for the attached plastic tubing). These calculations were completed by simplifying the system to a "hole-in-the-bucket" situation.
Next, using the previously determined flow through the exit tubing, the flow through the orifice drilled at the center of the attached PVC cap is determined.
