Basic formula to calculate pressure drop 5

[salmon2]

Hi Experts,

Just got a task to do some calculation about our hydraulic control system. I have enough education to understand the dynamics, etc but almost never worked on such real problems.

Spent tody online and already got some ideas about how to calculate pressure drop in pipes. But need to know more cause our system got a lot of components such 90 or 45 deg elblows, branch and running tees, enlarger/reducer without approach lines (abrupt change on diameter) etc. Wondering if anyone can point me at here I can find the formula to calculate those. I don't mind seting up my own spreadsheet or matchcad or matlab, whatever , but available spreadsheet is certainly welcome.

Also a basic question, is there a max limit for flow rate in a pipe given a internal diameter? What is limiting factor if any? How to calculate it?

Thanks a lot in advance.

CFD = basic formula for pressure drop? That's a new one on me.
