Picture of the Day: Water Pipe Burst Causes Flood In Pyeongtaek
An underground water pipe measuring 1,000 milimeters in diameter bursts in Pyeongtaek, Gyeonggi Province, on Jan. 31, 2015, flooding the area for hours. (Yonhap)

Hey, Yonhap! Keep it simple. One meter is much easier than 1,000 milimeters.
Just build a ten million micrometer concrete circle around it 1100 millimeters high and call it a fountain.
If it is located less than a few furlongs from a park and it runs more frequently than a fortnight, it could become an attraction.
How many cubits high would the fountain shoot in the air?
How many hectares would the nearby park be?
Is that right across from the AK Plaza?
How many hogshead of water were they talking about again?
20,000 Leagues Under The Bus?
“How many cubits high would the fountain shoot in the air?”
That would depend if it shot straight up… or made an arc.
That was by Dungbu apartments, near McDonalds in Songtan.
Thanks Nomad!
“That would depend if it shot straight up… or made an arc.”
CH went ballistic on us! đŸ˜‰
“How many hogshead of water were they talking about again?”
Think about it. You already know the pipe has a circumference of 3141.592653mm which leads to a cross section of 7.763 microacres. Find the water pressure in drachms per square fathom. Then calculate the flow in square furlongs per Julian day or fluid scruples per century. Multiply your answer by the length of time the water flowed in millifortnights. With proper conversion fractions in your equation, all units will cancel, leaving you with hogsheads, which, as you well know, are simply hexafirkins or 769.23 millipuncheons.
Alas, we had no such concerns in antediluvian Pyeongtaek.
I was about to post the exact same comment. Beat me to it…..
“I was about to post the exact same comment. Beat me to it…”
Then you would have had wrong math, too. I just noticed it should be 776.3 microacres rather that 7.763… a glaring mistake I can only attribute to hurried carelessness and lack of attention to detail.
In one glance, anyone can notice that:
1. A one billion picometer diameter pipe has an obvious cross section of one pi billion picometers.
2. An acre is just over 4 trillion square picometers.
3. In an operation anyone can do in their heads, the answer is obviously based on three forths, or roughly .75.
4. In another easy operation, cancel the zeros between a billion and a trillion and the answer will be in the x10^3 range… or milli.
5. As every high school student knows, .75 milli is 750 micro.
6. With an actual calculator, a more precise pi, and the exact number of square picometers in an acre, we can find that our in-head rough calculation of .75 is actually .7763… an acceptable margin of error for rough in-head calculations.
7. This gives us .7763 milliacres, 776.3 microacres, 776300 nanoacres, 776300000 picoacres, 776300000000 femtoacres, 776300000000000 attoacres, 776300000000000000 zeptoacres, 776300000000000000000 yoctoacres…
…or 776300000000000000000000 chickenheadoacres… a proposed but currently non-standard SI prefix… in which its rapid and enthusiastic adoption has been somewhat hampered by the realization that it reduces every SI unit past the Planck’s limit… making it a meaningless sub-quantum measurement… though it could perhaps be useful in calculating observed granularity arising from quantized angular differences in photon vectors, based on the Planck’s length, from objects at the edge of the observable universe… which suggests some disturbing hints at the true structure of reality.
I’m surprised you didn’t catch that.
Honestly I did. I was just being polite…..
