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.

the diagram does appear to take into account the radius of both the piston and the tool diameter

so i'm not quite sure what you mean

 

but your xls. calculator will be fine, thanks

I made a simple Excel sheet for calculating rocket pressing pressure. It's simple to use and takes into account holes in ramers.

That's a great tool. I love the spreadsheet. I wish I had thought of it!
