What is the volume of a human?

What is the volume of a human?

What is the volume of a human?

(OP)
Does anyone have access to a credible data source that lists the volume occupied by a 50th percentile human body?

RE: What is the volume of a human?

Fill your tub up - submerse yourself and yell "Eureka".  Clean up the mess and measure the water.

I beleive it was Archimedes that figured that out about 2,000 years ago or so.

Since we are something like 96% water - at 175 lbs / 62.4 lbs water / cubic foot.... Something around 3 cubic feet??  

Seems a bit low as I look at myself....

RE: What is the volume of a human?

How exact do you need to be?  Are you talking actual volume taken by the body itself?  I would think that would be very easy to calculate, given that the SG of the body is very nearly 1 depending on the state of the lungs.  50th percentile weight should be readily available from many sources.

RE: What is the volume of a human?

You better factor in food and alcoholic consumption, if applicable, before using the trusted equation below

volume = mass (50th percentile person) /density (water)

If everyone is willing to go home tonight, submit themselves to Mike's experiment and report back in the morning that would be sufficient.

My quick tape-measure approximation of myself, approximating torso, arms and legs as cylinders yields 2.3 cubic feet.

I am sure that the Army has subjected numerous soldiers to a dunking, and the data is published - I don't have access to any human factors info at the moment.  

 

RE: What is the volume of a human?

I "heard" that the average human can scream around 100 dB, how's that for volume?

RE: What is the volume of a human?

Darn Mint, you beat me to suggesting something like that.

KENAT, probably the least qualified checker you'll ever meet...

RE: What is the volume of a human?

DVD that is very funny LOL  

RE: What is the volume of a human?

In the pool I can sit on the bottom with lungs deflated.  Or I can just about float with lungs inflated.  So I reckon I have the same density as water on average.  Volume = mass/density.

50th percentile human mass is much harder to get information about.  It's probably very location-dependent.

RE: What is the volume of a human?

Yes, 50th percentile human mass varies with spacetime.

RE: What is the volume of a human?

Mint I have to ask the obvious question. Why in the world are you wanting this information? Are you disposing of bodies, again?

Luck is a difficult thing to verify and therefore should be tested often. - Me

RE: What is the volume of a human?

Quite a mundane need actually.

If you have a room full of people, how many cubic feet of air do they displace?

RE: What is the volume of a human?

People are not closed systems to displace air, rather intake and out-gass as continuous functions.

RE: What is the volume of a human?

Civliperson,

I was not interested in their respiratory rates.  I wanted to know what I stated - how much air does a human body displace.

RE: What is the volume of a human?

Well, I think my volume varies greatly from a Sunday afternoon (after a good weekend of praying to Baco party smile) to a Thursday (after paying my respects to the gym for a week sad).

Now, I do think that the average volume varies a lot depending on your geographical region, and very gender specific. Where is you 'research' focused at? I have taken a newfie to Japan and trust me, the volume difference is far from similar (more like a two to one)

Now, Civilperson got me thinking.... If I am floating on my back and pass gas, do I get propelled or just sink....? Gotta try it.
