Hello everyone,
I have been studying the derivation of specified static pressure outlet boundary condition in finite volume method for incompressible flows from Textbook "The Finite Volume Method in Computational Fluid Dynamics:An Advanced Introduction with OpenFOAM and Matlab "by F. Moukalled , L. Mangani and M. Darwish.
I have a question regarding the derivation (attached). Equ(15.141) simplifies to
Vb = VC
is that true? and if so, what is the benefit from Equ(15.140) then?

Thanks in advance
