Relationship between differential pressure and flow 2

[ris2]

What formula is used to calculate flow using differential pressure in pipes? Are any other variables taken into consideration?
Thanks.

Be a bit ealborate

Darcy's equations is usually used. There are other variables:

viscosity, density, pipe roughness, pipe diameter, etc.

Please download PDFs with all equations.

Good luck !

maybe you should take a class in fundamental fluid dynamics?
