Pipe Flow Calculations Forum

I have found an online calculator at http://www.pressure-drop.com/Online-Calculator/index.html. This calculates the pressure drop for a given flow straightener geometry using a perforated plate with thickness with circular openings inside a larger diameter pipe. It doesn't account for the spaces bet...

I would like to calculate the pressure drop across a flow straightener. The flow straightener consists of a tube bundle of 121 pipes of 50 mm NB sitting in 750 mm pipe. The calculation would have to take into account the inlet and exit losses of each pipe and the gap between pipes and the pressure d...
