help with an unconventional flowbench design

[cklug123]

Hello everyone, first time poster so I hope I've come to the right place!

I'm trying to build/correct a flowbench that an intern made for testing airplane air valve gaspers, so I assume my needs are slightly different from how you typically build them for car engine cylinders/engines-

Attached is an excel sheet with all my calculations and every rabbit hole I've gone down in an attempt to trouble shoot it. I figure I'm at the point where I could use some feedback from some experts.

I realize it's a lot of data and whatnot, but I appreciate your time and any extra eyes that could look over what I've got/where I'm at and maybe point me in the right direction or let me know if I'm missing something glaring

Thanks!!

Never knew what those air valves were called now I do . . . we didn't have those on C-130's that I worked on.

Beyond my pay-grade of flowbench design. I know there are some on here that have worked with blow-down style of flowbenches so it might take a few days for someone else to chime in.

Yep totally understandable. especially around the holidays I'm sure everyone is busy making family plans, etc

Thanks bruce, I'll wait for some other input/feedback!

I did a little cfd just to explore some potential issues with the design. Someone may find it interesting! It's a work in progress tho
