A reciprocating compressor or piston compressor is a positive-displacement compressor that uses pistons driven by a crankshaft to deliver gases at high pressure.
Clearance Ratio: It is the ratio of clearance volume to the swept volume.
Clearance volume: It is that volume which remains in the cylinder after the piston has reached the end of its inward stroke.
Swept Volume: Swept volume is the displacement of one cylinder. It is the volume between the top dead centre (TDC) and bottom dead centre (BDC). As the piston travels from top to bottom, it "sweeps" its total volume.
Calculation:
Given:
Since. the maximum volume = Vs + Vc
The swept volume is 8/9 times the maximum volume.
⇒ Vs = 8/9(Vs + Vc)
So, the correct option is (3).
