Question 6

typically only
move gas due to its natural
ability to be compressed.

Answer 6

Compressors

Question 7

have the ability to
move liquids or gases.

Answer 7

Pumps

Question 8

where the compressing and displacing element (piston or diaphragm) has a reciprocating motion.

Answer 8

Reciprocating Compressors

Question 9

are machines in which two intermeshing rotors, each in helical configuration displace and compress the air

Answer 9

Screw Compressors

Question 10

are machines in which axial vanes slide radially a rotor motor mounted eccentrically within a cylindrical casing

Answer 10

Sliding-Vane compressors

Question 11

are machines in which two straights, mating but non-touching lobes impellers trap the air and carry it from intake to discharge
