Friend,

I was checking the document ISA S20-1981 and the page 42 is concerning to orifice plates and flanges, this sheet show us the fluid data considered in order to do the calculus necessary for the orifice plates.

Right now I´m working in create a excel sheet with this formules in order to understand very good the orifice plate factors. I´m using for liquid flow the formules showed in the book from Lessons In Industrial Instrumentation By Tony R. Kuphaldt <----Excelent Instrumentation Reference

I hope this help

JP

Other good sites are:

http://www.omega.com/literature/transactions/volume4/T9904-07-DIFF.html#diff_1

http://www.efunda.com/formulae/fluids/calc_orifice_flowmeter.cfm#calc

Actually, performed comparison analysis between different approaches and found the online calculator I mentioned in previous post had best correlation to actual test data

Yes. See Perry, "The Chemical Engineer's Handbook", any edition.
