CFM Calculator for Compressed Air – Fluid-Aire Dynamics

Web12.4.1 Compression and cooling. Centrifugal compressors are the natural choice for compression of large amounts of CO2. The compressors will have a polytropic efficiency of 80–85 %. One casing (stage) can increase the pressure ratio up to five fold, e.g. from 1 to 5 bar; however, 3–4 is more energy-efficient. Web3) Finally, recalculate the polytropic head, gas power, and polytropic efficiency based on the corrected gas composition as well as the corrected inlet & discharge pressures and temperatures. The new values calculated under the reference conditions are referred to corrected performance. The constraints mentioned in Step 2 are known as follows:
