• water

• temperature

In which of the below, compression ratio is less?

• Single stage

• 2 Stage

Compression ratio is the ratio between ____ and ____.

• discharge pressure & suction pressure

• suction pressure & discharge pressure

• swept volume & clearance volume

• All are correct

A smaller clearance volume will ____ the compression ratio.

• decrease

• increase

• damage

• split

What is the advantage of multistage compression?

• lower work done to compress the air

• increase thermal stress

• easier to maintain water film

• increased compressor size

Volumetric efficiency is the is the ratio of actual volume sucked by the compressor at the inlet to ____

• bore

• stroke length

• swept volume

• clearance volume

Higher clearance volume will increase the volumetric efficiency of the compressor.
