Compressors cfm

How to work out the cfm of a compressor myself thinking its the amount of air going into the pistons and not the pis out or how long it can deliver that pis!

Its a q on my auction and here's what I know about the unit

3 hp - 2.2 kw
115psi
50 litre tank

You could safely say 12 - 15 CFM, somewhere towards the middle probably.

it's a craftsman 13, the 13 means 13CFM.

hpx 4 or Kw x 5 is rough rule of thumb for capacity. cfmdecreases as psi increases andvice versa.
