Fulchino Vineyard

[AlFulchino]

Dean..i am STILL laughing! Wow...talk about putting a wine thru its paces..my goodness!

Thanks for the report on the Vinturi...this is a gift for my friend Pete, that helps me w the vineyard. He will greatly enjoy.

 

[Goodfella]

Well Dean.... You were right about making us cringe!!!

 

[AlFulchino]

next time i am at a table and a sommelier says i'll be right back'

i will say...."leave the bottle'

 

[Dean]

Try some of those tricks at home. You will seriously be surprised at how they open up a tight wine. I know it sounds extreme, but it actually works too!

has anyone ever seen this......i must have learned something like this back in physics...but i don't seem to recall it....starting to wonder if my winery is in some weird vortex like they have in some parts of the world where gravity is altered

i have two 150+ liter primaries of signature blend fermenting from juice i held over from earlier in the year ( a few months ago)....

when i place my hydrometer in the center or in any part of the fermenter tub that is away from the edge of the primary, the hydrometer starts 'travelling' to the outside

now probably this has always occurred and i am just noting it because i am leaving it in longer to get temperature readings

my best guess is that the bubbling action is doing it...but when i place it in the center, then i assumed pressure would be equal on all sides and it would sit still

any physicists here?

 

[Brewgrrrl]

That is especially interesting, since the lowest point of the liquid would actually be the center. Hmmm.

 

[AlFulchino]

what do you mean 'lowest point of the liquid'?

 

[admiral]

I suppose it means that any liquid in a container assumes a concave surface as the sides of the container cause the edges of the liquid to rise (I guess from adhesion). Think about when you read your hydrometer in a hydrometer tube... you want your hydrometer in the center at the lowest point to take the reading.

 

[AlFulchino]

wait a minute...

the surface is maybe 36 inches across on each tub....your saying that the center is lower than the rest of the surface?

i can understand some of the liquid *climbing* right at the wall...but i cant see a difference in the ht across the rest of the surface...that would confound laws of physics that i do understand....also *if* the center *was* lower then the hydrometer should float to a lower place...wouldn't it?

this is all funny....watching the hydrometer literally travel across the tub

Uknown phenomenom

 

[AlFulchino]

and by the way..i am not drunk

 

[admiral]

Al, I think the answer is in here... somewhere.

[Dean]

It will be lower in the center by about 1 to 2mm due to the meniscus action of liquids in a vessel (suface tension). The moving to the sides effect is not that strange, and this will happen with large volumes of liquid.

You think you are stationary as well as the liquid. However, you are not. You and the liquid are actually moving in a circular motion around the earths axis at an average speed of 29.783 km/s or 107218 km/h. When coupled with the earth's magnetic fields, all liquids get a bit of swirling effect. This effect gets way more pronounced and visual when draining out of vessel (look at a toilet).

Due to the liquid rotating, you are seeing a centrifugal force effect on the hydrometer.

 

[AlFulchino]

Great....fascinating.....and that has me at some other sites along the same theme

my first new thoughts based on reading is that compression of the liquid molecules is greater at the center of the surface, while liquid at the walls is less compressed....then i wondered about the almost invisible vapor just above the surface pushing out in all directions......i just submitted the same query to

kinda the same as to why the hydrometer always stops spinning with the numbers away from you.

 

[grapeman]

Somebody has too much time on his hands if he sits around thinking about this stuff! LOL Better get busy with something Al. You must have something to do there even in this cold weather. If not, come on over and I can find a few things for you to do.

"kinda the same as to why the hydrometer always stops spinning with the numbers away from you.

"

damn if that isn't the straightest truth

****

Rich, you mean you dont sit and stare at our must all day long..just to make sure all is well?

I thought that only happened to me!!

 

[ibglowin]

Happens (almost) every time!

Shaping upto be a veryyyyyyyy longggggg winter it seems
