Thanks. I can use spreadsheet like this, however in imperial units. So I spent some time converting your spreadsheet to imperial units. How do I email it to you?

Click on your display name in the upper right and select "Support / Download Purchases". Then, select "Support" on the left menu. Enter a new support request and attached your Imperial units version for me and I'll upload it here for others to use.

I can not find the orgianl paper. So the most important factor I consider Cf is developed from the correlation? This correlation covers the dynamic flow of gas inside the pipeline itself? Thank you very much for your answer.
