I need a brief explanation of pipeline flow conditions that the Darcy-Weisbach equation can be applied and how this application carried out?
On the above question I specifically interest in application of the equation to gas flow
Interesting
Dear Ogbarode Ogbon
the Darcy–Weisbach equation is an empirical equation is used to find the pressure drop due to friction in pipes.
What else do you want to know?
Regards
Ahmed
The Darcy-Weisbach calculates the head loss in laminar or turbulent single-phase or multiphase flows. The pressure Loss according to DW formula writes
Dp=-Landa*(L/D)*Ro*U**2/2
Lamda is the friction coefficient that dépends on the Reynolds Number and its formulation is différent for laminar and turbulent flows

In terms of CFD, we often analyze the stability of the error using Von-Neumann analysis, especially for FDM based problems. Should we follow the same approach for a compressible fluid flow using FVM ?
