The bathtub problem
May 28, 2020, 2:48 PM
|
|
A grown man is fully submerged in a bathtub. The tub is 100% full, such that a single drop will cause the tub to overflow. For the point of this let’s say he just exhaled, and can hold his breath for several minutes.
Now, the man, who is averagely endowed, gets an erection.
Does the tub overflow?

It's merely blood flow from one part of the body to another. The appearance of increased mass in the penile region will be offset by the equivalent, nearly imperceptible loss of blood mass, and thus water displacement, across the rest of the body.

What if the blood for your peter

doesn't come from any cutaneous or subcutaneous means? What if it pulls all the blood from something that has the same displacement with or without blood, such as your bones?

In the same vein of dinking I think it would overflow.

The blood behind a rib cage or in his head moving to his dink would likely displace water.

I’ve thought this as well, but do you have to account for surface area when determining displacement of water?

He's not displacing any more water erect, or FBcooch sized

His weight doesn't change. Weight displaces water, not size.

So a 1lb square steel block and a 10 lb square
May 28, 2020, 2:56 PM

steel block that are the same size will displace more water?
I find that hard to believe, but don't have the science to back it up.

How about this: one is solid, one is hollow.

One clearly weighs more, but both displace the same amount of liquid.

[ in reply to Incorrect...a large man-size balloon ] |

You are correct. It’s a volume thing. The water must displace by the volume of the object that get submerged... or the density must change of the object submerged.

Ships are rated at tons of displacement.
May 28, 2020, 3:26 PM
|
|
As the water they displace is equivalent to their weight. There are about 5 other measurements that get confused with that, as that usually is their actual tonnage--or what they can carry.

Lets say a ship is rated at 1000 tons. That is the weight
May 28, 2020, 3:46 PM
|
|
of the water it displaces, but it IS NOT the weight of the ship. The ship is much heavier, but it's construction, shape and weight are what determines the displacement, not the weight alone.
Make sense now...you are mixing buoyancy and displacment...

"The displacement or displacement tonnage of a ship is its weight based on the amount of water its hull displaces at varying loads. It is measured indirectly using Archimedes' principle by first calculating the volume of water displaced by the ship then converting that value into weight displaced."
