vacuums

do

not

suck

They dont

High pressure pushes

@the21cat RIP I thought you were a flat earther lol

I was trying to get you to admit that there could be a pressure gradient

it was way easier than expected... but then you're not a FE

FE'ers, how long does it take to fly from Argentina to Australia?

21 cat. Yer loonier than a 3 dollar bill

a pressure gradient indicates a container

every container of pressure has a gradient

why would we deny the pressure gradient when it is characteristic of a container?

lmao gas fills its container so why would there be a pressure gradient in a container

it should be constant

and it isn't constant on earth because we're not in a container

but it's not lmao

¯\_(ツ)_/¯

literally all pressurized containers have a gradient

The pressure gradient would be in any container that is in a gravitational field. It's just that in most situations, the gradient in air is too small to worry about and it is ignored.

You can determine the gradient the same way you do pressure underwater. You just multiply the depth of the fluid by the density. For very large columns, the density of air would vary. But for a small container, we can assume it's nearly constant, around ρ=1.225kg/m3
That means near sea level, if the pressure at the bottom of a container is 1atm or about 1013mbar, the pressure 1m higher would be less by the weight of that amount of air.

ΔP=ρgh
ΔP=(1.225kg/m3)(9.81m/s2)(1m)
ΔP=0.12mbar
1m up in your container, the pressure is less by about 0.01%.

huh

that's actually kinda illuminating

it shows that even with constant density atmosphere, you could get a pressure gradient

imagine having to prove we aren't in a container

Imagine having to prove we are

"second law of thermodynamics!"

I mean actually proving it’s existence

what is this debate about

Wether there is a dome or not

It’s not really a debate at the moment

ok what is your opinion

No existe

ok i guess we have nothing to debate about xd

Lol

If we were in space all the air would be gone

It isn't gone thanks to gravity

@Citizen Z how come?

Entropy

Entropy is the reason we have a pressure gradient

I don’t think you understand entropy citizen
