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?
Also what would the general rig up look like?
Cheers
