23) Cylinder clearance in a compressor should be

as large as possible

as small as possible

about 50% of swept volume

about 100% of swept volume

Answer is:

as small as possible

gauge discharge pressure to the gauge intake pressure

absolute discharge pressure to the ab-solute intake pressure

pressures at discharge and suction cor-responding to same temperature

stroke volume and clearance volume

Answer is:

to accommodate Valves in the cylinder head

to provide cushioning effect

to attain high volumetric efficiency

to provide cushioning effect and also to avoid mechanical bang of piston with cylinder head.

Answer is:

increases

decreases

remains same

increases/decreases depending on com-pressor capacity

Answer is:

compressor efficiency

isothermal efficiency

volumetric efficiency

mechanical efficiency

Answer is:
