if you are lying on your back this will always happen. When not filled with blood dicks are vacuums which will float well.

did your bladder displace any of the water priorhand? in no, then the water level will rise

Thats really the heart of the question


e: The bladder is inside your body i think it displaces water on account of being in your body which is displacing water

Important question : are you breathing?
Also, what ratio of water and piss?

Full or empty, your bladder isn't displacing water outside of your body, so pissing in the water should raise the water level. Its like putting a solid container of fluid into water - if you drain the fluid into the water, the water level rises, because the container stays the same size, the water is replaced by empty space inside it. The outside dimensions of the container/your body remains the same.

You arent breathing because you cant do that underwater. The water is already a mix of water and piss, its not important how much.

No, it will not rise. Your bladder cannot sustain a pure vacuum, it contracts and all the organs around your bladder will fill in the area. It might rise a tiny bit, but I wouldn't think it would be more than 5% of the volume added to the water.

you lose some mass but the volume your body is occupying hardly changes. you might try to be all "gotcha but you'll float al ittle higher!!!" but thats seriously besides the point and nobody likes a trick question

i really have to pee, so what I'm gonna do is fill my bath with water and lay in it and pee in the water once its just about to flow over the edge and see if it flows over, this probably wont work because of the surface tension but if it happens then case closed

will post results in like 20 minutes

no retard because the additional weight inside the container makes it displace more water than it otherwise would have

like when a cargo ship is lower in the water when it is full.

otherwise melting ice would make all your poo poo overflow all the time

if i have two rocks of identical size but one is heavier they both displace the exact same amount of water and therefore push the same amount of water over the edge regardless of weight, as long as the entire volume is submerged. If it is buoyant the heavier thing will have more of it's volume submerged and basically what the nerd above me said

omg

lets make this easy for you smarties

chain a human being to the bottom of a large container full of water so that only the persons head is above water

have that person piss himself (or herself :wink:)

the water will rise.

mass makes a floating object displace more water because its simply heavier. in this case, it has zero relevance when a person is touching the bottom of the container, or bathtub, or as the title suggests : completely submerged since all the volume the person takes up in the water is maxed out so to speak

the only way the water wouldnt rise is if a cavity forms on the outside of your body when you take a piss, to account for the volume being expelled by your genitals. since that doesnt happen on any healthy human being, the water will rise.

the only possible way the water wouldnt rise is if the person was floating and perfectly still, pissed, and then rose ever so slightly due to the loss in mass. and of course that doesnt account for the million significant ways other bodily functions affect buoyancy

wrong

the only thing that is debatable is whether or not your body deals with the vacuum created by contracting or it can just withstand that amount of pressure in it's system when dissipated but keeping the volume of the body constant

If you're completely submerged, and you piss, one of three four things could happen:

1) When you pee, the piss leaves your body and then adds to the volume of the tank. The lack of piss in your bladder then causes your bladder to contract (because a pure vacuum would implode your bladder) which reduces the pressure inside of your stomach which then makes your entire abdomen contract somewhat to balance out the low pressure in your abdomen. This means that the added volume of the piss equals the negative loss of volume from your abdomen shrinking to compensate for the vacuum in your bladder. The water level remains constant.

2) When you pee, the piss leaves your body and then adds to the volume of the tank. The lack of piss in your bladder causes your bladder to contract like before, but your body can deal with the low pressure inside of the abdomen, causing no loss of body volume. The water level will rise.

3) #2 but in partial, the water level only rises somewhat. Your body contracts some but deals with some of the pressure.
