    i need to convert normal liter (Nl) into cfm.

    the pressure is 6 bar and room temperature.

    Normal liters are measured at 1.01325 bar (101.325 kPa) and 0 C. But liters are a measure of volume and cfm a measure of volumetric flow, volune/time.
    1 cu ft = 28.316 8466 L

    However, your "normal" liters need to be converted to actual liters at flow conditions. Assuming your room temperature is 25 C (77 F), take
    Nl x 1.01325bar/6bar x (273.15 + 25 K)/273.15 K
    for actual liters at flow, then use cubic foot conversion above.

    BUT, in English units, the volume is usually stated at atmospheric presure, not output pressure, and at some other standard temperature and they call it SCFM. In that case, ignore the pressure correction and ONLY use the temperature correction above, replacing 25 with the standard temperature, if you can find it.

        Re: nl to cfm

        I am just trying to figure out the required CFM for our machine so that I may purchase an air compressor.

        the value that I was given was 350 Nl, the temperature in the formula looks pretty accurate for us, and I am apparently too stupid to do the formula correctly,

        our machine is at 5.5 Bar.

        any help would be appreciated
        PLEASE HELP ME!!!!

          You need a time associated with that 350 normal liters. If it is per minute, same as your cfm, just divide by 28.3.
          If the compressore can take a week to move 350 L, you don't need much compressor at all.

              400 Nl/h at max 9 bar air pressure and room temperature is 24 C need to know how many cfm is it.

                1200 NL/min = ???CFM

                      From your post: "However, your "normal" liters need to be converted to actual liters at flow conditions. Assuming your room temperature is 25 C (77 F), take
                      Nl x 1.01325bar/6bar x (273.15 + 25 K)/273.15 K"

                      If using 6.0bar, instead of the "standard" 1.01325, wouldn't you factor the other way?:
                      Nl * 6.0bar/1.01325bar

                        No, at 6 bar pressure, the volume will be less (to compress the gas)
