ddewees Posted March 15, 2014 Share Posted March 15, 2014 Just be aware, that picture is misleading. You need the radius of the cylinder that the fluid is pushing on, not just the radius of the part that you can see. I've never taken one apart (yet), but I believe they can vary. I would encourage you to learn the formula yourself, it's actually not too difficult... and makes solving for any type/size tooling an easy process. I used to struggle understanding what I was trying to figure out, but then one day it just clicked and all made sense. Link to comment Share on other sites More sharing options...
dave321 Posted March 16, 2014 Author Share Posted March 16, 2014 You need the radius of the cylinder that the fluid is pushing on, not just the radius of the part that you can see. . the diagram does appear to take into account the radius of both the piston and the tool diameterso i'm not quite sure what you mean but your xls. calculator will be fine, thanks Link to comment Share on other sites More sharing options...
Zmuro Posted March 20, 2014 Share Posted March 20, 2014 I made a simple Excel sheet for calculating rocket pressing pressure. It's simple to use and takes into account holes in ramers. Rocket Pressing Calculator.xlsx Link to comment Share on other sites More sharing options...
