his sailing ships andturn the blades of his
windmills.

Sailors and shipbuilders knewthrough countless ears of

set a sail for ma!imum

shape better than another was
of little interest to them.

Intermittent modeofcompression is cclic
in nature, in that a
specific 1uantit of
gas is ingested b
compressor, actedupon and discharged,
before the ccle is
repeated.
Continuous compressionmode is one in which the
gas is moved into
compressor, is acted
upon, moved through the
compressor anddischarged without
interruption of the flow at
an point in the process.

(n dnamic compressors energ is transferred from a moving
set of blades to the gas.
Aecause of the dnamic nature of these compressors, the
densit and molecular weight have an influence on the
amount of pressure the compressor can generate.
#he energ takes the form of velocit and pressure in therotating element, with further pressure conversion taking
place in the stationar elements.
