So as a side project for my professor, I'm supposed to 1) build a recirculating simple pipe bend 2) experiment and get data 3) do hand calculations via fluids equations (Bernoulli) 4) simulate with solidworks 5) compare results Restrictions: budget and availability of finding products. Thinking of getting everything at Home Depot/Lowe's. Design can be anything but pipes at least 3" dia. It sounds simple, but I had to research crazily to understand how to make this all work. If anyone can give suggestions/advice/revisions on improving any part of the steps, I would really, really, appreciate it http://tinypic.com/view.php?pic=2lc6vlw&s=8#. http://tinypic.com/view.php?pic=2lc6vlw&s=8#.U8hi4vldX9N A very rough rendering of what I have in mind. The pipes would be raised and propped on a PVC frame. The pipes would be within ~3.5'x3.5'x3.'5 box size 1) Which submersible pump to use? Maybe 500gpm? 2) How to connect pump to pipe? 3) Suggestions on which simulation program to use? I only have FloXpress on Solidworks. Tried to use Autodesk CFD, but somehow my SW works don't load to CFD. I don't have Flow Simulation :( Thank you so much! I shall be waiting desperately for replies.
