i need to no how to calculate the cfm of my air compressor and the ratio at which it need to works in correspondence with the psi.
Michael, the rule of thumb is you get about 4 CFM of compressed air at 90 PSI for each HP of electric motor size.
Since I have no idea of the make or model of your air compressor, I can offer no more than that.
Please see the sitemap page for links to pages that provide much more info.
CFM & PSI

Why/how does the CFM increase as PSI decreases and vice versa?
Mickey, very good question, and one that has been responded to many times on this site.
There are a number of pages that address this issue, and rather that retyping all the info here, why not visit this page?
I can tell you that there are a number of methods to calculate this, some suspect (the one I suggested?) and some quite complex.
Please have a look and then come back with your comment.
