QUESTION2 Ala. A single-stage double-acting air compressor delivers air at 7.5bar. The pressure and temperature at the end of suction stroke are 1bar and 25°C. It delivers 2.2m3 of free air per minute when the compressor is running at 310rev/min. The clearance volume is 5% of stroke volume. The pressure and temperature of ambient air are 1.03bar and 20°C. Take: index of compression = 1.25 and index of expansion = 1.3. %3D %3D Determine: 2.1 volumetric efficiency of the compressor; 2.2 diameter and stroke of the cylinder if both are equal; 2.3 indicated power of the compressor and Brake power (B.P.) if the mechanical efficiency is 85%. 2.4 Draw the P-V diagram will all the relevant information.

A single-stage double-acting air compressor delivers air at 7.5bar. The pressure and
temperature at the end of suction stroke are 1bar and 25°C. It delivers 2.2m3 of free
air per minute when the compressor is running at 310rev/min. The clearance volume
is 5% of stroke volume. The pressure and temperature of ambient air are 1.03bar
and 20°C. Take: index of compression = 1.25 and index of expansion = 1.3.
