8) The lubricating oil in piston-type compressors is always found in minute amounts in the cylinder bore; compressor operations must always b aintained well below the Auto ignition temperature (AIT) of the oil to prevent explosion. A particular lubricating oil has an AIT of 365°C. Compute ompression ratio required to raise the temperature of air to the AIT of this oil. Assume an initial air temperature of 25°C and 1 atm. y for air is 1.4. O 4.6 O 9.8 O 11.9
