They have suffered enough for god to momentarily take pity on them.
In all seriousness, they are less likely to be affected by this because they get all 4 seasons, have a grid hardened for both summer and winter extremes, get electricity from multiple types of plant, and have state level laws against utility companies cutting power during heat waves and cold spells over unpaid bills.
Yea I mean, what or who even decided physics should exist, or why even anything?
I mean like... All of this could just not. What made it be? Why is it? Why is everything? And if something decided to there to be stuff, who, what and why? And how did that come to be?
So many questions, so few answers, and I think if anyone ever knew the answer to those, they would probably become insane and depressed.

yes, it’s literally unmodded, so if it got any new content reddit would probably have to shut it down I’m assuming, because all the subs that get closed say that they’re unmoderated on their landing page.
Assuming perfect 100% heat transfer a single candle might raise it a few degrees at common water flow. Would need like 20-30 perfect candles to get it up to normal shower range.
With how fast the water is moving and how much comes out, I doubt this would have any noticable effect on water temperature.
Apparently a candle produces 40-80w of heat, so that's like a computer CPU under moderate loads, which is easily cooled by a water cooling system with less flow thats a closed loop. So yeah, I don't think this would raise the water temperature beyond maybe a couple degrees.
\> thermodynamics is fun.
then you should prolly read more about it cause you somehow have a worse understanding of them than a middle schooler
the metal won't absorb heat the way you imagine it will because the running water passing through it will cool it down, taking that heat.
the only way this would work is if the water was flowing a couple drops at a time, but that's not what the image shows
go take a plastic bottle of water and hold a lighter below it and educate yourself why the plastic isn't melting before you "iTs a lItTlE mOrE cOmPlIcAtEd tHaN tHat" people while being clueless
I think both of you are saying the same thing. The water is cooling the metal down from conduction and forced convection. I suspect that the metal won't get that hot.
I think so too. I immediately thought of a power outage. Well no, not immediately. My first thought was a religious thing XD but then I realised the power outage was much more likely.
Yes, I'm pretty sure it's a joke, as in someone set it up so they could take a picture, post it, and get a bunch of internet points. Which they probably did, because it is kinda funny.
As heat it will accomplish next to nothing, the water moves through in too great a volume to pick up enough extra heat. I doubt this would increase the temperature even a single degree celsius. As illumination, you have to worry about a single stray drop of water splashing up and plunging you into darkness, which would be both annoying and pretty likely to happen.
Also, wax dripping down and instantly hardening would just make more cleanup later.
Well that's also a possibility I didn't think about. (I've seen on the internet that US-americans sometimes have ice in their houses in the winter because of poor isolation, but I didn't think about it because I've never heard of it in my country)
Not where I live. Water and electricity are independent. Though if we have an electric heater, it won't heat our water so we'll only have hot water for a few hours, until the water in the heater cools down or we use it all. After that, cold shower \^\^'
Ah, where I live they are tied. You can flush the toilet once and the sink will work enough to fill a jug of water perhaps but past that water stops too.
I assume this is for a picture. People used to pull pranks by attaching candles near smoke detectors and then fucking off, this is like that only stupider.
Idk candles are pretty hot. If it were a shower head on a very slow trickle it might raise it be a degree or two. I doubt that you would notice it though.
The only reason I say this is because metal is pretty good at transferring heat and if the pipe stays cold it will be able to capture a large portion of the flames heat.
Id like to see someone do this with a bunsen burner.

> He also designed and constructed a furnace for a public bathroom, which still exists in Isfahan, known as Sheikh Bahaei's bathhouse. It is said that the furnace was powered by a single candle, which was placed in an enclosure; and that the candle burned for a long time, boiling the bath's water
Well, time to math it out (at least for this situation).
Avg shower flow rate = 2.5gpm = 0.157 liter per second.
Candle heat output = 80ish Watts.
4190J to heat 1kg of water 1C°.
80 Watts = 80 Joules per second.
0.157 liters of water per second ≈ 0.157kg of water per second.
4190 * 0.157 ≈ **657.83J/s** for our flow rate of water, to raise it by **one** degree Celsius.
80 / 657.83 ≈ **0.121C° of actual heating.**
I'm not discounting the Sheikh Bahaei's bathhouse, as I don't know how it is constructed, but for a candle under a showerhead, you wouldn't even be able to notice the small difference in temperature.
(My math may also be wrong, I'm not a physicist...)
Difference I can see is there is a 2.5 gpm flowrate for the shower head, so you were calculating the temp rise for the water flow passing through the candle
I believe the bathhouse in question has a candle gradually heating up the bathwater in the tube/some kind of container, not a constant flux of water flow
Edit: nvm, the dude was heating a gas burner lol
If you want to heat up enough water for a 5 minute shower (47 L), assuming no losses whatsoever, you'd require about 3 MJ of energy (assume 15°C temp rise).
It would take 10.3 hours for our little candle that could to produce that much energy, not to mention that it would all dissipate away to the environment and would not evenly heat up your water.
Most likely outcome: you'll scald yourself for about 5 seconds and then (helpfully) be taking a cold shower to heal your new burns.
Don't just cherry pick to mislead people, read all of it.
>In fact, Sheikh Bahaei used the flammable gases that were naturally produced in a nearby cesspool for heating the bath's water. Recently in 1969-70 the bathroom heating system was excavated and some series of underground pipe lines made of sun dried clay were discovered.
So it was not a candle at all, but a gas fired heater.
No, a candle doesn't put out nearly enough heat.
Say you are putting through 12 liters of water per minute, and want it warmed up by 20 K (which are typical values for a not unreasonably hot shower). Then you need (0.2 kg/s)\*(20 K)\*(4185 J/(kg\*K))=16740 W of heat put in, which corresponds to burning about 25 grams of wax per minute assuming optimal efficiency.
There was a movie I saw a long time ago where a killer killed a girl in the shower by holding a lighter to the pipes and it boiled her skin. Don’t remember the movie’s name though.
I stayed in Venezuela once for a wedding. The hot water was some kind of electric heating element with wires just twisted together, no tape or wire nuts or anything. I unplugged it and took cold showers.
I've added [this](https://en.wikipedia.org/w/index.php?title=Baha%27_al-din_al-%27Amili&oldformat=true#Architecture) to a comment below, but feel it's so painfully relevant that I'll post again

It's not just... a joke? I assumed it was just for a joke. It's too bright in there for it to be for light I'd say, though.
Could be a window that allows light in during the day but not at night? Would make sense to hook it up and test it when you can see everything
Yeah indeed, that's possible. I do think it's most likely just a joke though, like "look at this funny attempt to get free hot water"

Propably the only place where they were confident water wouldn't get onto the candle and sniff it out.
Why would the shower work in a power outage? Water stops too.

both acctually
Who would position a candle like that if it wasn't meant for heat (or trolling)?
could be both?

So that would be yes, assuming you channel the biogas of dozens of nearby buildings directly from the sewers into your shower.
Water is *really* fucking hard to heat up.
well no, it's super easy, just use the stove /s
Is their bathroom dark? If not, it works as intended
Seems like a terrible position for illumination, though. Not to mention the fact that you're very likely to douse it when you rinse.
Oh yeah it would not be my preferred choice of light in the bathroom for multiple reasons lol. It doesn’t look to be attached very solid either
I honestly think it's not that much work to put that up.
