Thank you for your reply Ceptimus.
Just so I'm clear... Pressure drop is equal to volume-flow x resistance. Therefore I imagine that resistance could be in units such as Pa.secs/m^3 ?
I don't think cooling effects will be an issue for our system but I take your point.
Thanks for the replies so far. There is effectively a chamber between the two as the T-piece where the transducer nozzle connects is quite a large part relative to the size of the tubes. I'm doubtful of any effects due the mouth are dominating the readings as the flow's are very low and as I...
It looks like my ascii diagram got butchered as the forum code removes multiple spaces.
Pressure is read in between the two tubes (where the '+' is) .

Hi All,
I've come across something that surprised me but I'm sure has a logical explanation...
I have a two small ID tubes that have exactly equal impedance to air flow (for the purposes of the discussion the flow is 2ml/min). I connect them in series with one end of the system exposed...
