Vaporizing a Human Conditions https://www.thoughtco.com/chemical-composition-of-the-human-body-603995 Okay, First off. To vaporize a human thoroughly at once, let's assume the temperature change is 1800┬░F or 982.22┬░C https://www.cremationresource.org/cremation/how-is-a-body-cremated.html Average body temperature is 97.7┬░F-99.5┬░F or 36.5┬░C-37.5┬░C, giving us the average of 98.6┬░F or 37┬░C. https://en.wikipedia.org/wiki/Human_body_temperature So the temperature change is by 945.22┬░C http://endmemo.com/physics/specificheat.php https://en.wikipedia.org/wiki/Human_body_weight The average human is 62 kilograms. STEP I We will start with water. https://en.wikipedia.org/wiki/Body_water 60% of human mass is water, or 37.2 kilograms. http://www.engineeringtoolbox.com/water-thermal-properties-d_162.html The heat capacity of water is 4.1813 kilojoules per kilogram Plugging the values into this calculator Specific Heat energy is 147023640 joules We will use this calculator to find the latent heat of the water, which says water has a latent heat of 2264.705 kJ/kg. Plugging in the mass of water gives us 84,247,026 joules Adding these two values together we get 231,270,666 J STEP II https://www.itis.ethz.ch/virtual-population/tissue-properties/database/heat-capacity/ Average amount for body fat is 2.348 kilojoules per kilogram Fat seems to be 17% of body mass, or 10.54 kilograms going by the numbers shown Plugging it into the specific heat energy calculator, we get 23,392,229 joules STEP III Protein makes up 16% of body mass, which means it makes up 9.92 kilograms of the body https://www.itis.ethz.ch/virtual-population/tissue-properties/database/heat-capacity/ Muscle has a heat capacity of 3.421 kilojoules per kilogram Plugging it into the specific heat energy calculator, we get 32,077,288 J. STEP IV For minerals, it makes up 6% of body mass, or 3.72 kilograms. We will use bone for this, specifically cortical bone, which is 1.313 kilojoules per kilogram. https://itis.swiss/virtual-population/tissue-properties/database/heat-capacity/ We get 4,616,795 J STEP V Carbohydrates make up merely 1% of human weight, or 0.62 kilograms https://www.researchgate.net/post/W...s_for_liquid_amorphous_glass_and_solid_states Heat energy of sugar (carbohydrate) is 1.255 kilojoules per kilogram.

[KLOL506]

I still think it could look a bit cleaner IMHO

 

[Antvasima]

Should I lock the References for Common Feats page again?

 

[Jasonsith]

Should I lock the References for Common Feats page again?

I am okay now. See if other calc members are okay too.

Again, anyone else please look at the real pages first.

 

[KLOL506]

The real page uses 945 degrees celsius instead of 945.22. A small issue to fix.

The char part is fine tho.

Anyway, I've contacted Spino to take a look.

982.2 minus 37 equals 945.2 tho.

 

[KLOL506]

1800 degrees F is 982.2222 degrees celsius actually.

But the results are basically negligible so eh.

A change from 982 to 982.2 can be visible but not 982.2 to 982.2222. This I can agree.

I will have to sleep now (despite my insomnia) ttyl

 

[KLOL506]

Aight, take care, Jason. Your health comes first.

 

[Antvasima]

Are the rest of you fine with this?

 

[Spinosaurus75DinosaurFan]

I'm fine with it too.

 

[Antvasima]

Okay. I will lock it then.

 

[DeathstroketheHedgehog]

For the Real World's bullets, we know that their kinetic energy is an extreme lowball of their actual potential.

So wouldn't it be safe to put 'at least' for their tiers, and if there's proof of a higher tier (such as a sniper bullet going through a wall), couldn't we calc that and add it as a tier? If not, at least a "likely" or "possibly" tier?

 

[Jasonsith]

According to this site, the ratio of steel to concrete is 100kg:130kgCould the apportioned vaporisation values of iron and concrete be applied to the vaporisation values of reinforced concrete?

Done a rough calculation myself. Please check.

AFAIK: The dangerous part of a bullet damage is on its pressure. With a good shield the damage done by a bullet is largely equivalent to a punch with the same attack potency.

 

[Jasonsith]

4 * Tensile strength of wood * Elactic section modulus / Length of the beam

But work would be much lower than just force times distanse

Some pepple just made a calculation. As this may affect a lot of other calculations and may even set a model for shearing objects other than sawing off them, I think people here may wish tk havea better look.

Since this calc itself is for a classic character to get a profilefor himself, I will transfer it once you give green lights.

 

[Ugarik]

Well it definatly bending and not shearing. You can tell this by the shape of the crack in the middle.

And the formula above is not so hard to upderstand. All you need to know is hooke's law and how force lever works to make sence out of it

 

[Psychomaster35]

What would be the formula for ripping something in half (like rock) with both hands to get LS? (Here would be the general idea of what im talking about)

 

[ChemistKyle89]

Hello all, please peruse this concerning various mechanical properties of sheetrock / gypsum board. Also, this has some common building material densities.

 

[KLOL506]

Seems we still don't have a value for mild steel or carbon steel on this site.

 

[Antvasima]

That should probably be fixed.

 

[KLOL506]

Nothing to really fix tho, it's just two materials we lack. They'd be just minor additions if anything else.

 

[Antvasima]

I meant that the lists with fragmentation, pulverisation, and vaporisation values might need to be updated.

 

[KLOL506]

Oh.

 

[ChemistKyle89]

This might need a recalc, since our standard assumption for human body surface area is 0.68 m^2 (6800 cm^2), not 0.95m^2. Also, Head Length is 19.7 cm for males and 18.7 cm for females, according to Wikipedia.

 

[Spinosaurus75DinosaurFan]

Wrong. 0.68 m^2 is the cross-sectional area, which is only 40% of total surface area usually.

 

[ChemistKyle89]

I meant to say cross-sectional area. Since the calc divided the surface area in two, I assumed they were going for cross-sectional area...

It also doesn't change the fact that it's weird they used 7/8 of the Head Height to estimate Head Length...or where they got the Head Height number to begin with...which according to wikipedia should be an average of 23.2 cm (Male) and 21.8 cm (Female), not 23.9 cm...I assume they got the number from here and used the 99th percentile to define average...when the number for Head Length is readily avaliable.

 

[Spinosaurus75DinosaurFan]

Should be corrected then. Cross-sectional area is definitely not 50% of total surface area even if the number they used is correct.

 

[DeathstroketheHedgehog]

If you're on a planet with higher gravity, would your weight affect what you input as mass for kinetic energy and force?

Like running 30 mph on Earth compared to 30 mph on a planet with twice the surface gravity, would your kinetic energy and (if you ran into a wall) force increase?

 

[Thelastmlg]

Like running 30 mph on Earth compared to 30 mph on a planet with twice the surface gravity, would your kinetic energy and (if you ran into a wall) force increase?

I believe so, with higher gravity your weight increases, so this charge would require more speed, and since you are as fast as on earth, you would technically be faster than just 30 mph if you were with your normal weight.

So on earth you should be capable of running faster than 30 mph so your 30 mph charge on earth wouldn't b your limit and thus weaker than the charge on the higher gravity, where you are actually on your limit.

I'm not a physics expert though so take thid with half a grain of salt

 

[Ugarik]

no, there's a difference between weight and mass. Even if you are ten times heavier moving horizontaly shouldn't be any harder with the same mass.

(Recalc on Human-Shaped Hole) - How's this look? {Should any other materials be added? Concrete maybe?}

A Human-Shaped Hole
A common gag in fiction is that someone gets slammed towards a wall so hard that a human-sized hole is left.

The human body has an average cross-sectional area of 0.68 m^2 or 6,800 cm^2

Average Human Head Length: 19.7 cm

Volume: 6,800 cm^2 * 19.7 cm = 133,960 cc

Rock

Fragmentation = 8 J/cc * 133,960 cc = 1,071,680 J (Wall Level)

Violent Fragmentation = 69 J/cc * 133,960 cc = 9,243,240 J (Wall Level)

Pulverization = 214 J/cc * 133,960 cc = 28,667,440 J (Small Building Level)

Steel

Fragmentation = 208 J/cc * 133,960 cc = 27,863,680 J (Small Building Level)

Violent Fragmentation = 568.5 J/cc * 133,960 cc = 76,156,260 J (Small Building Level)

Pulverization (Low) = 300 J/cc * 133,960 cc = 40,188,000 J (Small Building Level)

Pulverization (High) = 1000 J/cc * 133,960 cc = 133,960,000 J (Small Building Level)

Concrete/Cement

Fragmentation = 6 J/cc * 133,960 cc = 803,760 J (Wall Level)

Violent Fragmentation (Low) = 17 J/cc * 133,960 cc = 2,277,320 J (Wall Level)

Violent Fragmentation (High) = 20 J/cc * 133,960 cc = 2,679,200 J (Wall Level)

Pulverization = 40 J/cc * 133,960 cc = 5,358,400 J (Wall Level)

Reinforced Concrete

Fragmentation = 10 J/cc * 133,960 cc = 1,339,600 J (Wall Level)

Violent Fragmentation = 61.2 J/cc * 133,960 cc = 8,198,352 J (Wall Level)

Pulverization = 610 J/cc * 133,960 cc = 81,715,600 J (Small Building Level)

 

[KLOL506]

Looks good but values for concrete and reinforced concrete would also do nicely.

 

[Spinoirr]

Shouldn't all Red vs Blue characters have small buliding level durability thanks to one of the main characters getting thrown through multiple steel walls from cargo containers that made human shaped holes

 

[WeeklyBattles]

When did that happen?

 

[Spinoirr]

this episode

 

[KLOL506]

That hole in the steel wall looks a lot bigger than "human-sized".

 

[Agnaa]

Being thrown through thin steel walls and making human shaped holes in them is not what this feat is calcing.

To scale to this standard feat, you need to be embedded in a human-shaped hole of that material. Not make a human-shaped hole in a thin wall of that material.

 

[WeeklyBattles]

Yeah those walls are thin, though a lot bigger than just human sized. A calc for that specific feat would be better

 

[KLOL506]

For that specific feat, just assume standard shipping container wall thickness and pixel-scale the wall with whatever stuff you can find lying around.

 

[Jasonsith]

We may see here for the dimensions of containers in the real world.

Assuming it is an average length of a 40 foot (12.18 m) container that is being concerned, length = 1218 cm, height = 239 cm

Width of the wall = 25 mm = 2.5 cm with a further "corrugation" of 2.5 cm

Material "thickness" occupied = (2.5^2 + 2.5^2)^0.5 = 3.535533906 cm

Might as well throw in "energy to Dettroy a shipping container"

Will do it by this weekend.
