I thought that you might've meant the non-time-varying component of the velocity. Thanks for clearing that up. So, with the original question I asked, if one were to put...

So, I too, like the OP am confused about obtaining the pressure drop. If the BC at the outlet is p=0, do we then integrate the total pressure (or, density-normalized pressure x density) and then...

BC at the inlet and a gage pressure=0 BC at the outlet? I'm just thinking that a choke valve cannot have a uniform flow distribution at...
