Hypothetical question!

[Viri]

So, let's say I somehow obtained a portal gun and a suit that can handle immense pressure.

One day I decide to go to the bottom of the Challenger Deep, because, fuck it, why not? I shoot a nickel sized portal on the ocean floor of the Challenger Deep. So, I resurface, and shoot another portal facing a brick wall! So, what happens now? Would the nickel sized shot of water smash through the wall? How far would the water be shot?

Spoiler

I have no idea why I am asking this. I must be high...

You should start collecting a couple of each animal and building a new ark.

Pressure = Density x Gravity x height
Density of sea water is 1024kg/m^3
Gravity is 9.8m/s^2
Depth of Challengers deep is about 11km
So pressure is about 110MPa or 1086 atmospheres
Force = Pressure x Area
Area of a US nickel = pi x radius^2 = 3.1416 * (1/2 x 21.2 x 10^-3)^2 = 0.000353m^2
Force = 110,000,000 x 0.000353 = 38,830N = 4000kg of force.

I think you just did this guy's math homework.

More like physics.

Being a pedant I have to take issue with the "kg of force"

To try to be less of a joyless bastard though I might as well link a fun, but relevant, video

It would be a great class if they are using word problems involving video games

Haven't finished my fluid mechanic but it should be the same velocity as water falling from ocean surface to that depth. And without aerodynamics this means reach square root 2 * gravitational acceleration * depth and with 3000 m that should give you just over 240 m/s, which is more than enough to cut steel. 11km on the other hand will give you 464 m/s. But even just 500 meters should give you enough to punch through a wall. Of course once exiting the portal aerodynamics becomes a problem so there are some vaporization.
