It is well-known that the temperature of a gas rises while it is compressed as a result of the energy input in the form of compression work.

The concentration of the oil within the compressor is usually too low to create a real danger. However, the oil that collects on the inner walls of exhaust piping of the compressor may cause an explosion. Such explosions have largely been eliminated by using the proper lubricating oils, carefully designing the equipment, intercooling between compressor stages, and keeping the system clean.

Question

It is well-known that the temperature of a gas rises
while it is compressed as a result of the energy input in the
form of compression work. At high compression ratios, the
air temperature may rise above the autoignition temperature
of some hydrocarbons, including some lubricating oil.
Therefore, the presence of some lubricating oil vapor in highpressure
air raises the possibility of an explosion, creating
a fire hazard. The concentration of the oil within the compressor
is usually too low to create a real danger. However,
the oil that collects on the inner walls of exhaust piping of
the compressor may cause an explosion. Such explosions
have largely been eliminated by using the proper lubricating
oils, carefully designing the equipment, intercooling between
compressor stages, and keeping the system clean.
A compressor is to be designed for an industrial application
in Los Angeles. If the compressor exit temperature is not
to exceed 250C for safety consideration, determine the maximum
allowable compression ratio that is safe for all possible
weather conditions for that area.
