enter image description hereWe are a manufacturing plant and this is one query which we could not find the answer too. So, came here asking for help.

Problem: In the attached image, you can see the air/steam inlet from the top which then goes through the non-uniform duct which has holes all over where the yellow arrows go. So, the question was that:

a.) Will equal air/steam will go through opposite end holes? b.) If not, which side(Narrow/Wide) will be giving out more air/steam compared to the other one?

I did some research online and according to that the narrow side will provide less air/steam compared to the wide side holes. Need your help guys as this query both interests me and is part of my job too...

  • $\begingroup$ Why not measure the narrow side outlet velocity profile (pitot tube) and calculate the mass flow... the difference to the inlet mass flow will tell you. $\endgroup$ – user207455 May 15 at 11:56
  • $\begingroup$ You might post this to the engineering stack exchange instead. Also, add a reference to the online research that convinced you of your current conclusion. Finally, what background do you have and what principles are you applying to analyze the problem? $\endgroup$ – Jeffrey J Weimer May 15 at 12:32
  • $\begingroup$ I have a numerical model for the sprinkler with 10 holes. Maybe it will be useful. physics.stackexchange.com/questions/477796/… $\endgroup$ – Alex Trounev May 15 at 12:32
