Centrifugal compressors are used to pressurize and move gases through piping systems. Like centrifugal pumps, centrifugal compressors work by acceleration and imparting velocity to the fluid in the eye of the impeller. However, gas compression is accompanied by density and temperature increases which changes the calculations and selection factors. This workbook provides qualitative and quick comparisons and application notes for centrifugal compressors. It describes calculations and procedures to predict performance characteristics, especially head, discharge pressure and power.

This excel workbook presents formulae and data for :

1. General centrifugal compressor calculations

2. Useful Fan-Law relationships

3. Assessing the effect of one inlet condition change on compressor performance

4. Assessing the effect of multiple inlet condition changes on compressor performance

5. Assessing the effect of system resistance on compressor performance

6. Adjusting centrifugal compressor rated performance curve to actual inlet conditions
