Gas Side Pressure Drop Across Fin Tubes Gas Side Pressure Drop Across Fin Tubes
Provided for your use by HRSGdesign.com

The gas side pressure drop may be calculated by any number of methods available today, but the following procedures should give sufficient results for HRSG design. Refer to the previous pages for source of the correlations.
