The head loss in the tube was determined using the equations for major and minor losses. The equations used in these calculations were found in online AguaClara notes and in Frank M. White's Fluid Mechanics (6th Edition).
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).

Next, using the previously determined flow through the exit tubing, the flow through each of the orifice plates can be easily determined.

Then, head loss through both the tubing and orifice plates are calculated given user input for width and number of orifice plates along with the length of the desired tubing. This total head loss through the system is the summation of the head loss through the orifices plates and the head loss through the wider, encompassing tubing.
