remains unaffected

may increase or decrease depending on compressor capacity

(a) multi-stage compression

(b) cold water spray

(c) fully insulating the cylinder

both (a) and (b) above

ideal compression

adiabatic compression

botii isothermal and adiabatic compression

isothermal compression.

radial flow

axial flow

centrifugal

combination of above

cools the delivered air

results in saving of power in compressing a given volume to given pressure

is the standard practice for big compressors

enables compression in two stages
