Greg, thanks for the reply. I have a basic understanding of the subject, and have read Mitchell's article before - and I agree it's a good introduction. I noticed you FBRCH formula above and was just wondering how much the different approaches affect design decisions. I appreciate your point...
Greg
Are you able to provide more information on the estimation/determination of the force based RCH without a full analysis of the system?
Cheers
