I understand that as an incompressible fluid flows through a pipe with decreasing cross sectional area the velocity increases. This must happen for the mass/volume continuity equations to be true. Since the velocity is increasing though there has to be a net pressure on the fluid right? My question is - what's the best way to think about this pressure? Is it like pressure "buildup" because the flow is restricted? Or is there a better way to interpret it?(adsbygoogle = window.adsbygoogle || []).push({});
