comment Internal pipe flow - Pressure Drop
@Louis Thank you for the help anyway. I have not done any calculations with undeveloped flow either so this is my first time which is why its confusing. If it was fully developed then it would be very easy and I could in fact split the pipe into separate sections (for organization purposes) without having any difficulty

comment Internal pipe flow - Pressure Drop
@Louis So for undeveloped flow, I have an interpolation table that determines $f$ through Reynold's number and L/D. So I separated the pipe into like you said, a 3 ft straight, 2 ft bend, 3 ft straight and 2 ft bend. I then found the Reynold's number and L/D for each section to determine each section's $f$ and each section's Pressure drop. This did not end up being the same as taking the entire 10ft pipe and finding its L/D, f, and pressure drop. So separating the pipe gave me a different f at each section because each section had a different L/D than the entire pipe.

you are correct, I found my error in my derivation =D the resistances do turn out to be the same
