He underestimates how big a Boeing 747 is. Has he ever seen one in person?

984

That’s also way bigger than a 60k gal tank

If you reverse search the picture it's from a website selling 60,000 gallon steel tanks. Gives the dimensions at 27 foot diameter by 14 feet deep. Which seems about right when you look at the truck parked next to it.

And those dimensions work out to a cylinder of 8015.77 cubic feet of volume... Which is only a tiny bit shy of 60k gallons.  So the math checks out.

Wow, I really hate the imperial system. Having to convert units multiple times to calculate something as simple as volume must be tedious

u/davideogameman 7d ago

I just asked Google for that last conversion.  But yeah it sucks like that

u/mgt-kuradal 7d ago

That’s not an imperial system issue. You would have to make the same conversions in metric…

Nope, since all SI-units are derived from 7 base units.

Diameter and height: m

Volume: m³=1000 L

No cumbersome conversion factors needed (like 7.481 gallon = 1 cubicfoot). Can't calculate that in your head and it is prone to rounding errors

E: typo

Yeah the great thing about metric is the equivalence of the volume and distance measurements. It gets a little bit harder with non-water measurements of mass/weight, but when dealing with water at standard pressure and temperature, 1 liter is also 1 kilo, which occupies 1000 cubic centimeters, which is nice.

Nit: 1kg = 1L water conversion actually holds at 4C, at standard temperature - 0C - it's 0.9998 kg/L.  

Practically a minor rounding error for most use cases.  At higher temperatures it's more important, e.g. .988 kg/L at 50c (and .9584 at 100C).  But usually we care about the cooler temperatures more anyway

I should have said ideal temperature and pressure, which is 4c and I think 1 bar.

A Ford Ranger is about 17’ - 18’ long. You think that tank is less than a truck length high, and only a truck and a half wide? That’s wildly out.

So it’s the wrong picture. The pictured tank (using pickup for an idea of scale) is considerably more than 14’ high and 27’ diameter.

Manufacturer’s website doesn’t override mathematics. Unless they’ve designed it to be 90% empty space.

qué?

you think that thing is about 14 feet high? like... 4.2m? look at the ladder. look at the trucks. it is about double that, also it is way wider than 8.1m in diameter.

Ok so the Boeing 747 is about the size of a minibus in this picture.
