Thumb rules for piping design

Can you give me some reference (site/book) for handy thumb rules to be used in piping design, layout & stress analysis?

Is there a site specifically for popular piping thumb rules?

Use the 'Search' facility on this site. Choose keywords like 'stress', 'design' etc. There have been plenty of posts similar to yours, which Mr. Breen, Mr. Luf and others have answered in great detail.

Here is my contribution.
