This is a great example of where theory meets reality and things immediately get more interesting. Pressure drop due to friction is often glossed over in introductory material, so it is refreshing to see a first principles attempt to model it instead of relying purely on ideal assumptions.

I especially like that you validated your results against a real world reference chart. That comparison step is critical and often missing in early simulations. Even if the model is simplified, showing that the trends line up with empirical data is what builds confidence that you are on the right track.

Your observation about the lack of practical, end to end resources on real fluid behaviour is spot on. There is plenty on Bernoulli and Torricelli, but far less that walks through friction factors, diameter sensitivity, and how assumptions like average velocity affect results. This is exactly the gap where small, focused models like yours are valuable learning tools.

From a quality perspective, documenting assumptions and validating outputs against known references is very similar to how engineering teams test software models and simulations. Using something like Tuskr test management software can help structure those validation cases, expected ranges, and comparison data so experiments remain traceable as the model evolves.
