Experiment to determine maximum N2 flow rate through a 1/4 OD tubing

    Experiment to determine maximum N2 flow rate through a 1/4" OD tubing

    Measured rate of gas flow vs theoretical rate of gas flow

    I am looking to set up an experiment to determine the maximum flow rate of gas through a 1/4" tubing.

    I have a spreadsheet which calculates the theoretical rate. The modified Darcy equation was used to calculate the mass flow of gas through the tubing when choked flow is present.

    (Quick question - any other ways of calculating either better or worse?)

    I would be looking to achieve the following conditions:

    upstream pressure - 120barg
    downstream pressure - atm
    pipe ID - 0.125"
    Length of tubing - 600m (I know that a shorter length will create larger flow rates but is there any way I can reduce this length for ease of experiment and still get comparable results if the theoretical rate was calculated using 600m length?)

    Would Nitrogen be a good gas to use with this test?

    I have a flow meter which produces a digital read out of the results so would it be a case of connecting that to one end of the tubing and pumping nitrogen through the other end?

    Cheers
