Start pressure: p1=1 bar;

Volume: V=36m3;

Temp.: T1=T.

Now I need to increase the pressure to 6 bar, but the volume remains unchanged. So:

End pressure: p2=6 bar;

Volume: V=36m3;

Temp.: T2=T.

So volume and temperature remain unchanged.

What amount of gas (m3) do I need to add to increase the pressure with 5 bar (p2-p1).

Compressor gives 185 l/s, max. working pressure is 7 bar.

I know p*V/T=p*V/T but I'm struggling to calculate the required volume.
