Dear Ankur,

I'm wondering if you would mind sharing the bibliographic information on the paper included in the last worksheet. I'm interesting in 11.5 "the extended intersection points...appear to be about 20% of the length," resulting in the 1.20L term in the equation for the divergence angle. I'm likewise interested in the Figure 11.10.

Thanks for sharing this workbook.

Ankur,

Did you see that part in Rennels and Hudson where they say pressure drop in an ANSI reducer can pretty much be ignored because there is no bulk slowdown? Do you agree with that?
