Orifice in a Tube

Post by jfholm »

Here are some pictures of my orifice in a tube attempts. We were just cleaning to move so these are going to the trash heap. I thought I would post the pictures first though.

Move?

To the house with the dragstrip in the front yard?

Does this mean the flowbench is on hold again?

Hi Rick,
Yeah we had some major throwing away to do and some fixing up to get the house ready to put on the market. We want to make sure we get as much as we can.
One good thing is that I have located all the parts I had bought for the flow bench. :lol:

I hate tidying up.
I keep finding parts that I had intended to use for some future project or other, that never got started.

Once everything is put away and tidy, the work begins in earnest with these projects, and pretty soon everything is back in a huge untidy mess, worse than it was before.

This has taught me a big lesson. STAY ON TOP OF IT!!! When it was in a big disaster mode I would look for a part or tool and could not find it so I would get "pissed" and go buy a new one. Well now that we have everything found and together I have 9 hammers and about 10 tape measures etc etc etc :lol:

For some unknown reason I buy two of mostly everything. I have been that way all my life :)

they are running off of 4.5 inches of pressure drop? so need less vacuum? but have to convert up to higher inches of water.

You can have stable readings in a tube at higher pressures. I have ran mine to beyond 60"... :)
