The
compressors used in a gas turbine are typically of which type?
Centrifugal
Centripetal
Reciprocating
Axial
Axial
● The axial
flow compressors are mainly used in gas turbines because of their high efficiency.
● Early gas
turbines are employed in centrifugal compressors, which are relatively simple
and inexpensive.
● They are,
however, limited to low pressure ratios and cannot match the efficiencies of
modern axial-flow compressors.
Accordingly, centrifugal compressors are used today primarily in
small industrial units.
Hence, the correct
option is (D).
