Single-stage, single-acting reciprocating compressor takes in air at 1.013 bar and 15°C and delivers it at 7 bar. The compressor is handling a free air delivery amounts 0.3 m'/min. The polytropic index is 1.25 . The compressor rotates at 1000 rev/min with a mechanical efficiency of 87%. If the stroke/bore ratio is 1.2/1, and neglecting the clearance volume, then calculate: • Power of driving motor. • Cylinder bore size. • Isothermal efficiency. Draw the cycle on p-V indicator diagram.

Question
Transcribed Image Text:Single-stage, single-acting reciprocating compressor takes in air at 1.013 bar and
15°C and delivers it at 7 bar. The compressor is handling a free air delivery amounts
0.3 m'/min. The polytropic index is 1.25 . The compressor rotates at 1000 rev/min
with a mechanical efficiency of 87%. If the stroke/bore ratio is 1.2/1, and
neglecting the clearance volume, then calculate:
• Power of driving motor.
• Cylinder bore size.
• Isothermal efficiency.
Draw the cycle on p-V indicator diagram.
