Determine SCFM of gas flow

I have a nitrogen stream that I need to find out the max flow in SCFM from a 1/4" tube at 50PSI. What is the best way of determining this? I dont have a pitot tube, what can I do? I broke my anemometer trying to measure this.

Thanks,

 

If you want a 'real' answer I'm not sure it can be done very easily.  It will depend on the friction losses in the tube, which depends on configuration, length, surface roughness and even the shape of the exit in the end of the tube.  Sorry to not be very helpful.
