A new improved version of the spreadsheet related to equivalent length of valves and fittings with new and more accurate estimation of resistance coefficients for ASME B16.9 reducers is available at: http://www.cheresources.com/invision/files/file/258-equivalent-length-calculations-for-pipes-and-valves/

"Goal Seek" function of excel can be used to arrive at the blowdown valve or orifice size in the spreadsheet "Gas Pipeline Blowdown Time Calculator" by setting the blowdown time to the desired value

A quarter-million views on Ankur's Chemical Engineering Blog in less than two years. Thank you readers for all your support and encouragement. Will always strive to provide value for the readers.

Recently discovered that In Excel 2003, the limit for nested functions is 7 when trying to build more than 7 "IF" statements. Excel 2007 & 2010 allow you to have up to 64 nested functions. Can we upload Excel 2007 / 2010 files with file extension .xlsx and .xlsm?

Merry Christmas to all members of the "Cheresources" community. God Bless, and hope the community keeps growing

Dear Sir, I am a chemical engineering graduate and working in a natural gas based petrochemical plant. I need to calculate "cracked gas compressor's efficiency". The problem that I m facing is, how to update the value of Cp/Cv (=k), considering the changes in gas's composition (undergoing compression). As u must know, we deal with a mixture of H2, CH4, C2H2, C2H4, C2H6, C3, C4......n so on (say....nearly 8 major components). Also we have got 4 compression stages, so 8 terminal...
