A single acting reciprocating compressor runs at 360 rev/min and takes in air at SSL conditions and compresses it in two stages to a final pressure of 15 bar (gauge). The required Free Air Delivery is 3.4 standard cubic metres of air per minute. Each stage has one piston with a stroke length of 100 mm. Assume the index of compression and expansion is 1.23 for all stages and the clearance volume ratio is 0.04. Calculate the followings :

Transcribed Image Text:A single acting reciprocating compressor runs at 360 rev/min and takes in air
at SSL conditions and compresses it in two stages to a final pressure of 15
bar (gauge). The required Free Air Delivery is 3.4 standard cubic metres of
air per minute. Each stage has one piston with a stroke length of 100 mm.
Assume the index of compression and expansion is 1.23 for all stages and
the clearance volume ratio is 0.04. Calculate the followings :
Transcribed Image Text:(i)
The ideal interstage pressure.
()
The compressor isothermal efficiency and the heat transfer rate in the
intercooler to reduce the compressed air temperature to ambient.
(ii)
The compressor volumetric efficiency.
(iv)
The ideal indicated power.
(v)
The swept volume of each stage.
(vi)
The bore of each cylinder.
SSL conditions are 101.325 kPa and 15°C.
