(a) Characteristics of Reciprocating and Rotary Compressors:
Reciprocating Compressors:
Mechanism: Reciprocating compressors use a piston-cylinder arrangement to compress the gas. The piston moves back and forth, creating pressure and compression.
Operation: They operate through positive displacement, where the volume of the gas is reduced by the reciprocating motion of the piston.
Efficiency: Reciprocating compressors have high efficiency and can achieve high compression ratios.
Size and Capacity: They are available in a wide range of sizes and capacities, suitable for both small and large-scale applications.
