Download Flare Stack Calculations

* * * - - 1 Votes

MS Excel spreadsheet featuring flare stack calculations from API RP 521 based on both the Simple and Brzustowski+Sommer approach for comparison.

This spreadsheet was originally posted by Erwin Apriandi who is not a current member of the community.

In the Brzustowski’s and Sommer's Approach, the isothermal sonic velocity is calculated as per API 5th edition section C.3.3

isothermal sonic velocity = 91,2 (Tj/Mj)0,5


But the spreadsheet uses a formula that considers the ratio of specific heats

isothermal sonic velocity = 91,2 (Tj*k/Mj)0,5
