Abstract / scope
Covers blowers or compressors and exhausters of the centrifugal, mixed flow, or axial flow types, with and without intercooling, handling any vapour or gas the physical properties of which are reliably known. May be applied to any compression process, with or without bleed-off or sidestreams, which takes place in one or more casings. The theory used is based on the laws of similarity of fluid flow. The observation of these laws determines specific requirements for the execution of acceptance tests.
