I received an e-mail from Eng-Tips from your "Send a Comment to Latexman About This FAQ". I understand your message, "Can i pls have a copy of: Safety Valve with Ideal Gas.xls". Yes, you can. Unfortunately, my e-mail to you could not be delivered. The postmaster said your e-mail address was not correct.
Correct your e-mail address with Eng-Tips, and try again.
Or, put your correct e-mail address in the reply to a new "Send a Comment to Latexman About This FAQ".
Or, reply here, and I'll reply with my e-mail for a short while. I will delete my e-mail within 24 hours, because I don't want it public knowledge forever. I think we have a 24 hour window for editing, don't we?
