Comic Strips is a community for those who love comic stories.
The rules are simple:
- The post can be a single image, an image gallery, or a link to a specific comic hosted on another site (the author's website, for instance).
- The comic must be a complete story.
- If it is an external link, it must be to a specific story, not to the root of the site.
- You may post comics from others or your own.
- If you are posting a comic of your own, a maximum of one per week is allowed (I know, your comics are great, but this rule helps avoid spam).
- The comic can be in any language, but if it's not in English, OP must include an English translation in the post's 'body' field (note: you don't need to select a specific language when posting a comic).
- Politeness.
- Adult content is not allowed. This community aims to be fun for people of all ages.

Math checks out. ( 28800 ) ๐
Not sure I ever heard this angle before, but among all the impossibilities of Noah's ark, this is definitely a good one.
PS: in metric that would be approximately 10000 mm rain per hour.
So what does "equivalent to a firehose" mean in this case? What area per firehose? A football stadium per firehose? An Olympic swimming pool? An average room? A jar?
EDIT: I think it's about one firehose per 10x10 meter area, so like a couple of rooms worth of area. It's not that bad. I bet rainfalls like that do happen for a few minutes in taiphoons and such.
I assumed a firehose per area the size of a firehose edit: some quick googling says a 6cm firehose dumps about a cubic meter per minute, which works out to 500 meters of water per minute if we measured it like we measure rain.
30ft per hour is about ten meters per hour.
Yeah, no I would not say that is like a firehose.
Rain is usually calculated per m2.
1 m3 per minute is 60 m3 per hour.
10k mm rain per hour is 1 liter x 10k = 10 m3 per hour.
So I make it out to about a sixth of your firehose. Which still makes it way worse than any kind of weather you would call rain.
I'm not sure what other analogy would be closer?
Edit: Corrected to the quote I actually responded to.
No, it is a one dimensional number(excluding time) that works for any area. If you put two containers down in a rain, one 1m^2 area and one 1dm^2 area, both will collect water up to the same level.
Yes there will be 100 times as much water in total in the large container, but the height when spread in the container will be the same in both.
concentrating the water fall from a 1m^2 area into an area the size of a firehose is not how rain works. Rain happens spread out over the whole area.
When you calculate the volume, it's usually per m2. I quoted the wrong part.
So when you compare to a firehose, you must compare the volumes.
Tightly packed firehoses wouldn't make any sense, because that's not how firehoses work.
At least that was my interpretation.
a cubic meter per minute is what the firehose outputs, so thats over approximately a dm^2 not an m^2
which comes out to a 500m high column
Also known as 10m/h.
Or departing from the realm of the useful completely, that's water pooling at roughly 1/30 of the speed with which an elite cyclist ascends a particularly steep gradient.
With a catchment area of "planet earth", that's roughly 5,100,000,000,000,000,000 liters of water an hour. That's more than twice the amount of beer Lemmy Kilminster drank in an entire year!
