Please Make A Note: How Euler Derived the Momentum Equations

I found this great post explaining a great derivation important for Physics and Mechanical Engineering.

In this post, I will present Euler's derivation of the momentum balance equations for a fluid flow. Please note that I will use modern notation with a few modifications to the original derivation to clarify certain issues. Nonetheless, the core of Euler's derivation is maintained.
