Answer 1

a. An axial compressor is a dynamic compressor that contains a rotor with contoured blades followed by a set of stationary blades (stators).
b. A centrifugal compressor is a dynamic compressor in which the gas flows from the inlet, located near the suction eye, to the outer tip of the impeller blade.
c. A dynamic compressor is a compressor that uses centrifugal or axial force to accelerate a gas and then convert the velocity to pressure.
d. A liquid ring compressor is a rotary compressor that uses an impeller with vanes to transmit centrifugal force into a sealing fluid, such as water, driving it against the wall of a cylindrical casing.
e. A multistage compressor is a device designed to compress gas multiple times by delivering the discharge from one stage to the suction of another stage.
f. A positive displacement compressor is a device that may use screws, sliding vanes, lobes, gears, or pistons to deliver a set volume of gas with each stroke or rotation.
g. A reciprocating compressor is a positive displacement compressor that uses the inward stroke of a piston to draw (intake) gas into a chamber and then uses an outward stroke to positively displace (discharge) the gas.
h. A rotary compressor is a positive displacement compressor that uses a rotating motion to pressurize and move gas through the device.
i. A single-stage compressor is a device designed to compress gas a single time before discharging it.
j. A cylinder is a cylindrical chamber in a positive displacement compressor in which a piston compresses and then expels the gas.
k. An interlock is a type of hardware or software that does not allow an action to occur unless certain conditions are met.
l. Surging is the intermittent flow of gas through a compressor that occurs when the discharge pressure is fluctuating, resulting in flow reversal and instability within a compressor.
