Hi every one
I want to model flow inside a reservoir, with one inlet and outlet
the inlet of my reservoir is connected to the Specified pump so my pressure and flow rate are known, I use fluent software,
for modeling the inlet boundary condition I have two options
velocity or pressure inlet Bc
with velocity inlet bc, I have correct flow rate but my pressure is incorrect, and when I use pressure inlet bc I have correct pressure, but this time my flow rate is incorrect,
So what can I do????? and what is the best boundary conditions for reservoir inlet????

Thank you
