How powerful would a gate to the plane or water be? Assuming you made a gate to 1,000 miles down? Is there a limit to how fast the water would come out?
the water would slowly poor out so you could use it to drown someone or alter environments I guess
>>76945987I mean, there's definitely an equation to solving this theoretical using volumetric flux and multiplying that by the density of water. Think it involves partial differential equations? Dunno, never took fluid dynamics.
>>76945987Do you mean the energy of the water coming out? All of this depends on the gravity on the plane of water and the gravity and pressure of the location of the gate on the other side.
>>76946811There is some indication that plane of water has no gravity, just like plane of air. Otherwise, it being infinite in all directions, you would be crushed by infinite pressure and there could be no native life
>>76945987Who says water flows through the gate? Maybe there is a wall of water across the bounds of the portal from which water can be collected and moved, but does not actively flow. Like the surface of the sea.
>>76947010Okay, you can still have pressure without gravity but in order to calculate the pressure we'd need to know the density of the water and the temperature.
>>76946003That makes no sense
>>76947010>There is some indication that plane of water has no gravity No>>76947142Physics
>>76947306>PhysicsIt's a magical portal to a dimension that solely contains H2OPhysics as we know it does not apply.
>>76945987Depends on the setting
>>76947306>Physics>in a game where you can teleport into space, which automatically takes a 10-minute bubble of air with you
>>76947737>It's a magical portal to a dimension that solely contains H2OWhy is this meme so prevalent?>some things are magical, so that means physics don’t exist Lore wise gravity and pressure exist, please cease your retardation.
>>76945987>Is there a limit to how fast the water would come out?Yes. The maximum velocity of an incompressible fluid driven by pressure is the speed of sound within that fluid. This is because the speed of sound is, by definition, the rate at which pressure travels within a fluid. For water the speed of sound depends on temperature and salinity, but in general it is going to be somewhere in the range of 1400-1500 m/s.
>>76950823Concise and informative.This is the best post I've read this year, thank you.
>>76950745>Why is this meme so prevalent?Where is the meme here? Everything just stated to you was completely factual.>Lore wise gravity and pressure exist, please cease your retardation.And they're both frequently overcome by low level spells like Feather Fall or Levitation.Why do you think a magic portal to a magic realm is powerless to the effect of gravity and water pressure?
>>76945987If this is D&D, there is no "down" and the Elemental Plane of Water has a nearly universal level of pressure across its entire infinite size.
>>76951358>And they're both frequently overcome by low level spells like Feather Fall or Levitation.Okay and? Hate doesn’t change gravity. The assumption is that the plane of water has gravity (it literally says so in the D&D wiki) and that gate doesn’t affect gravity.
>>76955167Doesn't say things just spew forth from Gate either. For all we know there is a membrane that has to be intentionally crossed.
>>76955167Either gravity acts on all the water in the plane forcing it together until it collapses into an infinitely expanding black hole fed by the endless water supply or the plane has no gravity and all the water remains suspended at a point barring outside intervention. Which means it doesn't flow out until affected by another force.
>>76945987I think the water wouldn't flow out of the portal unless you were using a force to attract it. First, there's definitely no gravitational effect on the water of the plane of water while it's in the plane, because it's uniformly dense and there's no weird cosmic phenomena like it being a supermassive black hole. Second, portals in DnD generally act as membranes between realms, so the local gravittly, temperature and air pressure on your side isn't acting on the other side and also, say you open up a portal to a demiplane where there's huge wild magic energy, it has no effect on the room the portal is in. These two taken together make it almost certain that the water simply will not flow at all, except by force you put on it, and then it depends strictly on the kind of force you're applying. Any water extracted from the plane of water is suddenly subjected to the physics of your plane but all of the water still on the plane of water isn't, so you'd need to continually apply the force you're using to extract it. I imagine that's what some spells actually /do/ with the elemental planes, convert astral energy into the magical and physical forces necessary to transport and act upon substances in them.
>>76945987Of course, unless you're playing GURPS all you need to know is "water comes out fast".
>>76945987At 1000 miles down, the water coming out of that portal would be akin to a highly-pressurized tidal wave. anyone directly in front of it would most likely have all of their flesh peeled off their bones in an instant, and the room would fill up with water mere seconds after that. Depending on the structure, the room itself could be destroyed, as until the pressure equalizes a LOT of water is going to come out of that portal VERY fast - 1000 miles is a FUCKload of pressure - assuming you open this theoretical portal at the bottom of a 3-floor dungeon, everything on the bottom floor (including you) is dead, and anything on the other two floors is gonna need to swim. If the portal isn't closed the dungeon will become the source of a new river.And that's the OPTIMISTIC possibility - there exists no fucking structure that can withstand the force of 1000 miles of water pressure slamming into it - worst-case scenario the entire dungeon collapses under the force as a geyser-like spout of water decimates everything inside.
>>76955167>The assumption is that the plane of water has gravityIf you're talking about D&D it expressly doesn't have gravity. None of the elemental planes do. They're based on perception.
>>76960848Gurps is shit.
>>76961851Not how elemental planes or portals work. Even the statement 1000 miles down is completely stupid because you can't be 1000 miles down in a elemental plane.See >>76959293
>>76963084Shut the fuck up turbonigger - I was ignoring the fucking stupid 'plane of water' bullshit and focused on the 1000 miles down part, you absolute illiterate ass.
>>76945987I always pictured it more in an eldritch planet sort of way. If you go far enough down, eventually you'll reach the core, which is just infinitely crushing pressure and water. Go up far enough, you find a sort of horizon, but if you keep going up, eventually you realize the sky is water and you start technically going down again (even if earlier you were going up). In many ways it's kind of a flat earth sort of deal as if you stay on the horizon line (where for some reason it is lightened like sunlight) you're good. So it truly is infinite going on a X or Z axis, but if go on the Y axis, eventually the pressure will be too much to bear in either direction. Theoretically if you can get through it, eventually the pressure starts lightening up and you get to another horizon line. So yes, you can do that trick in Goblin Slayer in the Elemental Plane of Water, depending on how you set up the gate. And don't (you) me. I wanted a reason to have undersea nightmare vore Hell in the a reality that is literally completely filled in water (with the exception of a few bubbles caused by something)
A plane comprised uniformely of the same material would not have any pressure or density differences. You would have an infinite plane of one big infinite piece of ice. If the plane were not uniform, and the water had energy distributed at random, then you would have pressure, density, and temperature differentials and currents swirling within the plane.Opening up a portal into that plane may or may not see water flow in or out: it would depend on the properties adjacent to either side of the portal at any time. If the portal on our planes side were in the air, them water would flow into our world because its air vs water densities. However, if submerged, flow couls go both ways depending on conditions on either sideIts possible, given that its infinite, the water planes portal would be similar to ours and nothing significant would flow. However it is also possible, given infinite mass, that the water plane goes under a severe weather current, where a hyperdense storm of water flows near the portal. This would violently flow out into our world. Likewise, the reverse could happen and suck out our ocean.
