Pipe Bend Forces Due to Internal Pressure

09/21/2012 4:02 PM

When a pipe bend is subjected to internal pressure the pipe tends to want to straighten out. This phenomenon is what causes the Bourdon tube meter to to work. I am looking for the theory that describes the forces and resultant moment that the internal pressure causes.

Thanks,

Johan van Niekerk.

Thanks Joshi, I got some references from you I did not have.

It seems that this is a problem coming from many different applications. I refer to Yamamoto specifically who did his research on fishing nets- interesting.

regards,

Johan.

Johan,

Here's a link to a very good hydraulics textbook that will give you the methodology to solve the problem:

http://www.4shared.net/download/fbxuBEJp3BFkVF8dq1IjRp/A-TextBook-of-Fluid-Mechanics-and-Hydraulic-Machines-Dr-R-K-Bansal.htm

The pdf download is free. Once you download the *rar file you must go to page 286.

Good luck!
