142) In a single stage, single acting reciprocating air compressor without clearance volume, the workdone is maximum during

isothermal compression

isentropic compression

polytropic compression

none of these

Answer is:

isentropic compression

actual volume of the air delivered by the compressor when reduced to normal temperature and pressure conditions

volume of air delivered by the compressor

volume of air sucked by the compressor during its suction stroke

none of the above

Answer is:

Explanation:

The compressor capacity is defined as the volume of air delivered by the compressor, and is expressed in m³/min or m³/s.

Right

Wrong

Answer is:

free air delivery

compressor capacity

swept volume

none of these

Answer is:

Explanation:

The volume of air sucked by the compressor during its suction stroke is called swept volume.

constant with decrease in compression ratio

decreases with decrease in compression ratio

increases with increase in compression ratio

decreases with increase in compression ratio

Answer is:
