Because as I have always said you still have to move a volume of air. Moving (which implies acceleration) mass requires force. F = ma.

I gather from this that you haven't got the faintest of clues what perpendicularity has of an effect on forces.
I shan't bother trying to enlighten you anymore - you remind me of Drax the Destroyer in that regard.
-
@Rhywden No again. The pressure from the atmosphere can be considered equal on sides.
-
@Rhywden I do, but YOU are incorrect in this case because it isn't relevant.

Ad hominem attacks are the best you can do.

Well, you are a grade A moron. I don't even know why I bother.
-
@Rhywden You haven't disproved anything by calling me a moron. As I said to Tufty if you have a comment about this that proves me wrong, I am quite willing to accept I am wrong.
So far you just called me a dickhead. Calling me names, proves what I happen to think about you.
When your super physics brain works out Newton Laws of motion again ... please contact me.
Because so far you have demonstrated that you don't understand the laws of motion.

@lucas1 said in Air pressure inside restaurants:
@tufty It involved me pulling cages off the lorry and putting them in the right place for people that were stacking the shelves.
It was a perfectly fine job while at University.
I also worked in McDonalds "flipping burgers" ... are you going to try to shame me on that?
TIL that making a joke about someone working as a double entendre is "shaming" them.
Question, when you worked "flipping burgers", did you ever slip a pickle in one of them? How about special sauce?
-
@anotherusername we used to make such jokes back in the days.
One of my best mates got sacked for kicking a happy meal box.
It was a job when working at Sixth Form (college in the USA).
-
The fucking irony ...
Me - Ad hominem attacks are the best you can do.
You - Well, you are a grade A moron.

@lucas1 said in Air pressure inside restaurants:

WTF? No "shaming" intended; as @anotherusername pointed out, it was merely a double entendre. If you're ashamed of what you've done yourself, that ain't my problem.
@Rhywden You're 100% wrong on the sideways thing. If you want to try and argue that suction cups don't work sideways or upside down, though, I'd certainly be willing to stand around and laugh.
There's lots of things wrong with what lucas has said in this thread, it's amazing to me that someone can get through a university sciences degree and still only have a primary school level understanding of basic physics, but he's actually right on this one. Although not about "moving a volume of air". Just saw that bit. Bwahahahaha.
-

Don't believe you on previous behaviour towards me. As I said in the past you are disingenious.

Admits I am correct and then says I am a dumbass.
Classic @Tufty.

@lucas1 said in Air pressure inside restaurants:

Oh, go on, then. Tell me exactly how that's the case.
-
@tufty Because when I tried talking to you one on one you where as rude as you are now.
It said more about you than me.
It is fine if you want to project your negative personality traits onto me. Don't expect me not to tell you to fuck off afterwards.
-
lacking in candor; also : giving a false appearance of simple frankness : calculating
Not candid or sincere, typically by pretending that one knows less about something than one really does.
‘this journalist was being somewhat disingenuous as well as cynical’when I tried talking to you one on one you where as rude as you are now.
I'll remind you, fuckhead, that I was rude, but that I also warned you you'd just doxxed yourself. Make of that what you will.
-
@tufty i thank you for that. And if the positions were reversed I would extend the same kindness.
But you don't get a free pass for everything else.

Oh well, you're right. Been a while since I had to bother with pressures and stuff. On the other hand, regarding @lucas1 : Even a blind squirrel finds a nut once in a while
-
@Rhywden So you won't even admit you are actually incorrect. Jesus. You are the definition of hubris.

Dude, are you drunk again? Because what you're uttering can only be explained by either brain damage or some hallucinogens.
Probably both.
-
@Rhywden Nope. It just shows you up for the real person you are.

Yes. And? Want to run home to momma?
-
@Rhywden Nope, see previous response.
-
@lucas1 Well, the picture you're painting for yourself here ain't exactly a bed of roses either :)
-
@Rhywden Well I haven't be disingenuous and wrong so far, unlike you who have.
-
No, but you've been consistently wrong about the meaning of disingenuous.
-
@tufty nope.

So… have we established if there is a pressure gradient between the inside and the outside of the restaurant yet, or if it is just some mechanism in the door to encourage it to stay shut? (The overall depth of the atmosphere — and hence the absolute value of atmospheric pressure — is unimportant. The local gradient might matter. Or it could be some sort of mechanical resistance that disables once the door is more open.)
IOW, most of the discussion in this thread is dumber than a box of rocks.

I've seen some boxes of rocks (well, processed silicon) that were fair dinkum thinkums. This discussion… not so much.

Are you shaming rocks for being in a box?

@Luhmann Would you shame them in a house?

"Box of rocks".
Hmmm.
Rocks are made of silicon.
Put enough silicon bits in a box, arrange them properly, and you've got every semiconductor-based computer on the planet.

Eh, I dunno. I guess this thread could work as a temporary stand-in until the next proper flamewar.

There is probably at least a small pressure difference between the inside and outside, due to things like air conditioning and range hood fans, but most (external) restaurant doors have a hinge/spring mechanism that pulls the door shut, and the mechanism is probably usually a fair bit stronger than the force from the pressure differential.

I don't think it's the spring, because usually once the door is about an inch open it's a lot easier to open. That just screams air pressure to me.

Not necessarily. It could be a system that provides an initial higher resistance, but then once it reaches a certain point, the resistance drops off significantly. For another example, check out the range of motion of your car doors. They probably have three angles that they'll "pop" into (closed and near closed, half-open, and full-open), but those are separated by ranges where you have to push a bit to get the door to move.

Not to mention that you can feel the brief whoosh of air equalizing once you open it a little and break the vacuum seal.

That's called "farting" over this side of the pond, and it's frowned upon in restaurants.

I was chatting with my favorite Thai restaurant's owner a while back... one of those ADA "I make my business suing people" assholes made him change the tension in their spring. Now a good gust of wind opens the door.
edit: This was the same place where (same/another/doesn't matter) ADA asshole sued them because the sidewalk wasn't angled right. Instead of say a 3% angle (to curb) it was 5%. (something like that - point was, the change was incredibly small - I couldn't tell the difference after they had to rid the entire sidewalk out and replace it.
