So you have nothing to say on the radiant output of a human body?



It's less than the calories it consumes?
I'm not talking about the NET thermal transfer, or HEAT of the human body, ~100watts, I'm talking about the radiance. How much radiant energy comes off of a human body (my avatar being a graphic depiction).

No such thing as net heat. RDCF.

Now ITN will chime in with some fallacy BS but he has NO CLUE what the radiance of the human body is. Can't apply the Stefan-Boltzmann equation, can't calculate it at all. It is UNKNOWABLE to him.

Quite a lot of it depends on the capillaries. That's how the blood system transfers heat in the extremities.
That would be how a human body convects thermal energy internally yes.
Capillary relaxation is not convection. Redefinition fallacy.
tmiddles wrote:
But if we know the surface area, emmissivity and temperature of an object, including a living human, we can calculate the radiance using Stefan-Boltzman.

Stefan-Boltzmann equation:___P(out)=σeA*(T1^4)
(5.67×10−8J/s⋅m2⋅K4)(0.97)(1.50m2)306K^4=-723W

Your human is suffering from hypothermia.
tmiddles wrote:
Now ITN/IBD and other deniers like to end debate by claiming that since there isn't one fixed exact value available for surface area (I use 1.5m2),
There isn't.
tmiddles wrote:
emissivity (I use 0.97),
Random number. Useless.
tmiddles wrote:
and temperature (I use 306K)
Your test subject is suffering from hypothermia. Call 911 and begin treatment immediately.
tmiddles wrote:
that it's impossible to think about this.
You just have to throw up your hands and run out of the room.
Which YOU just did.
tmiddles wrote:
But you never will have a fixed and exact value for anything in this universe of ours.
A measurement has no range.
tmiddles wrote:
The surface area, temperature and emmissivity of the human body is easy to put a range on though.
A measurement has no range.

My point here is. They refuse to debate. They have no answer at all.

I would like to know if I disagree with your estimate of the radiance of a human body IBD. What is your estimate?

Off the cuff, 12.


Sea level varies from place to place in the world - keepit

Clouds don't trap heat. Clouds block cold. - Spongy Iris

Printing dollars to pay debt doesn't increase the number of dollars. - keepit

If Venus were a black body it would have a much much lower temperature than what we found there.- tmiddles

Ah the "Valid Data" myth of ITN/IBD. - tmiddles

Ceist - I couldn't agree with you more. But when money and religion are involved, and there are people who value them above all else, then the lies begin. - trafn

You are completely misunderstanding their use of the word "accumulation"! - Climate Scientist.

The Stefan-Boltzman equation doesn't come up with the correct temperature if greenhouse gases are not considered - Hank

:*sigh* Not the "raw data" crap. - Leafsdude

IB STILL hasn't explained what Planck's Law means. Just more hand waving that it applies to everything and more asserting that the greenhouse effect 'violates' it.- Ceist

Show your math.

Hint: you need to use the stefan-boltzmann equation to calculate radiance

I can walk you through it if you don't know how.

I didn't use any. You asked me for an estimate ... of something vague ... so I gave you a very rough off-the-cuff estimate of some vague notion.

Do you really expect me to do arithmetic? I hate arithmetic. What is it you really need?

Not for smokers. Not for junkies. Not for liars.
