Using the flow rate of 68 mL/min, the model (assuming no restricted flow) would require approximately 4 hours and 9 minutes to be emptied (4.16 hours). Below are graphs of the height of water in the constant head tank plotted against the amount of time elapsed each experimental run. It is quite noticeable that in each consecutive run, the constant head tank is increasingly more filled by the 4.2 hour mark, which is marked by the red line. Furthermore, the "peak" point (which means that the stock tank has finally been drained) takes longer and longer to occur in each run, as is signified by the blue line. Finally, it has been noted that on October 18th, the graph never reaches a "peak" because it has finally clogged.

Conclusions
The flow of water through the model becomes increasingly
