If we have a fixed velocity, we will compute a flow field that has this velocity inlet condition. The computed solution will give us the pressure at the inlet.

It is the pressure GRADIENT that drives the flow.&lt;\/p&gt;&lt;p&gt;With that in our minds, let us return to your question. If you change the operating pressure, what are you doing? You are simply scaling the pressure up to whatever depth you are at. The pressure and velocity fields will be the same. What will be different is the absolute pressure field, but this is going to be simply whatever the difference is between the given operating pressures.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-291669","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Let us talk a bit of theory here first.
