Hi,
Did you try your favorite search engine ?
To start with :
Hagen–Poiseuille equation - Wikipedia
https://en.wikipedia...igation systems.
https://en.wikipedia...isbach_equation
All equations are related to head losses.
Hagen-Poiseuille is specific to laminar flow
Hazen-Williams is used for water pipe networks ( empirical correlation) , examples : water distribution networks or fire fighting networks
Darcy-Weisbach is the reference equation for liquids in pipes.
Good luck
