Air flow changes in a pipe with the change in gas temp?

    nuclear reactor question

    air and non condensible gasses being removed from the condenser and processed through a treatment skid through a pipe.

    steady state value flow rate at 77 deg f is 30 scfm

    fixed the refer vault and now the temp is 15 deg for the gas.

    what will be the flow rate at 15 deg f?

    thanks....and this is not home work but real work...

    mass flow rate remains same. volumetric flow rate changes.

    Mass flow rate = density*volumetric flow rate

    density = f(Temperature)
