P1V1/T1 = P2V2/T2.

Looks familiar?

the temperature of compressed air @ different pressure & humidity conditions .

Anything that you like is the simple answer.

I think what you are after is the discharge temperature from each stage of the compression cycle. If this is so then the relationships below are valid. For simple calculation purposes for an air compressor you could probably ignore humidity and for a reciprocating machine use the first formula and the ratio of specific heats k (1.4 for air). This is accuarte enough in most cases.

That equasion is no good. The person asking doesn't know p2 or t2. So they end up with one equasion and two unknowns.
