Interesting question and maybe this is where im confused. The pressure difference would be the same but the friction in the tube would slow down the gas in the longer tube more leading to a lower mass output, correct?
Yes that is true. For a real answer i would probably need some CFD simulations. But i dont want to go too much into detail with it and just find out experimentally if it works the way i want it too.
Basically my question originates from the problem: Which leads to a flow which is 'longer'...
How do you know that? Sorry if the answer to this question is straight forward but it isnt to me. Ofc the pressure at the outlet is the same for both orifices but wouldnt the pressure drop in the center of the orifice be different because its size dependent? Maybe im just confused.
Regarding...
Hi! Thank you so much for the quick answer.
No the question isnt school related, i'm trying to develop a flow straightener element and trying to figure out the effect of combining different orifice sizes to the velocity profile and therefore the laminarity (if thats a word :D).
Yes you...
If a gas flowing through a tube would meet two orifices with different diameters in the same cross section, how much of the gas would flow through each orifice and what would the gas velocity be in dependence of orifice diameter?
