"Equality barometer". The Finnish violence monopoly dropped the question of violence within families apparently because results didn't support the feminist narrative. Few people are afraid of violence at home, men a bit more than women - exactly as the "academic consensus" would have predicted. imgur.com/a/PiuZwUG

[Question] is there a slim altimeter, barometer, compass watch?

I am trying to do some research on an ABC watch that is not as thick as a tuna can. All I can find are thicker watches.

I am looking for an ABC watch that is somewhat slim, solar, and 100 meter water resistant. I know Seiko and Casio may have a model that is not as thick but I haven't found one yet.

Question: I have an old Henry J Green Mercury-filled barometer that I am restoring. The mercury cistern & glass tube has some pin holes & breaks that need to be repaired. Any ideas on an epoxy/glue that will not react with mercury? JBWeld? N-Butyl Cyanoacrylate?, Etc.

I'm hoping this is the right place to ask, but would anyone be willing to help a newbie with questions about barometer repair?

In advance, please forgive me for any misused terms or general ambiguousness. I have never attempted to repair any kind of meteorological equipment but I know my way around simple machines well enough to try.

A couple weeks ago, I purchased an aneroid barometer from the local Goodwill, fully expecting it to have some kind of issue that may be repairable. If nothing else, it's awesome looking and is still on my wall in spite of the discovered lack of functionality.

Upon opening it, I found one small screw at the very bottom of the "arm" that had been loose enough to free itself and the tiny spring around the reading hand was bound up, but not beyond saving. After fixing these two apparent problems and reassembling the barometer as a whole, it still does not seem to display any kind of accurate reading, in fact the hand seems to stay stationary. Tilting or tapping the barometer only moves it in a way that suggests it's loose somewhere but I'm too unfamiliar with the device to pinpoint why. I have attempted some light research on my own and have attempted to set it properly for my area with not much success.

I would really like to fix this myself if possible for my own learning sake and if anyone knows how, I'd love to try it. Likewise, if it sounds like I need to have a professional fix it, please let me know. I'd hate to accidentally break it even further with my good intentions.

Question about atmospheric pressure and mercury barometer

I am trying to understand how pressure works, and have a question about the mercury barometer.

As I understand, the vacuum on top of the tube has no pressure. The mercury in the column is getting pulled down by gravity, and as it is getting pulled down by gravity it is pushing the mercury in the reservoir up but the mercury in the reservoir is getting pushed down at the same time by atmospheric pressure from the air.

My question is, if the reservoir has less surface area exposed to the air should that not affect how far the mercury goes up the column?

Look at this diagram:

https://imgur.com/5HMGTnK

Since in the second picture there is less area for the air to put pressure, should the mercury level not be lower? I know it will be the same amount, but I do not understand why.

Sorry if this is a misguided question, I never did physics in school.

[Question] Battery usage barometer is reading 100% Bluetooth and nothing else

Hey! So I'm running stock 7.1.1 with Magisk 10.2 and Franco Kernal. I started noticing that my battery life was getting dramatically shorter, so I checked to see what was using the most battery. Come to find, apparently, 100% of my battery is being used by Bluetooth, and if I charge at all that day, it may read 164% of battery is due to Bluetooth. This is true even if Bluetooth is off.

I guess this is a bug of some kind, but I can't find anything on the internet. Guidance would be awesome!

Question about Barometers/Altimeters

I'm looking to get a GPS watch and I'm a bit torn between two models. They're pretty much identical, with the exception of the barometer. I don't need a barometer or altimeter, but it's nice to have for sanity checks, knowing that you have 800 more feet of climbing to go before your get to your lunch break, or just looking and seeing how much butt you've kicked on a trail run. On the other hand, my knowledge of how they work, combined with reading the instructions for these watches leads me to believe that for them to be reliable and useful I'd probably have to set the reference altitude every time I go out. Frankly, that just sounds annoying, and I'd probably rarely use it if that's the case.

Anyone have experience with this sort of thing? Do you regularly have to reset things, or can you go for a while without having to fiddle with it?

Two questions about barometers/force diagrams
  1. If you invert a tube of mercury and partially immerse it in to a pool of mercury, the mercury in the tube will stay there because of the atmospheric pressure acting on the mercury in the pool. The weight of the mercury in the tube then has a downwards force; is this weight caused by all of the mercury in the tube, or just the mercury in the tube that's above the pool-level? If sea-level atmospheric pressure is 760mmHg, is that 760mm measured from where the tube enters the pool, or from the bottom of the tube? I.e. in this diagram, is h1 or h2 760mm?

  2. Let's say you have the above situation. Now you do the same thing but with a tube with twice the radius, in the same size pool. The mercury rises to the same height in either tube because the height it rises to is independent of the cross-sectional area of the tube, since pressure is force per unit area and its the pressure from the atmosphere and the pressure from the mercury in the tube that is being balanced. But isn't the situation with the bigger tube that there is a greater force downwards from the mercury (because there's more of it in the bigger tube), and the force on the mercury in the pool is somewhat lower, because the tube is taking up more room in the pool and so the atmosphere has less mercury to push down on. It seems to me then that while the pressure is balanced in both situation, the forces aren't, and so there should be some net movement. But this is wrong and I can't see why.
