How much weight is that guy carrying? If I recall, water is one of only a very few substances that gets less dense as it goes from a liquid to a solid... or am I having a brain fart? If that were a volume of water what would it weigh? 200 lbs?

It looks like about 12 cubic feet, so it weighs about 90 lbs.
ReplyDeleteit says 300 lbs on the picture, so I'm going to guess... 300 lbs
ReplyDeletethink of water molecules as shaped like jacks. above freezing the molecules can mingle, tip here to center there. at freezing, the molecules attach themselves tip to tip and end up in orderly rows and columns, which takes up more space than mingling.
Shit! I used to be able to do this shit in my sleep! Lets go with Jess. Check my math, because I am losing my marbles. Hell's bells - I am truly retarded now:
ReplyDelete12 cubic feet = .3398 cubic m.
Density of ice is approx 917 kg/m3
.3398m3 x 917 kg/m3 = 311.59 kg.
311.59kg x 2.204 lb/kg = approx. 687 lbs...???
I need to go flush my head down the toilet!!! I can't do math any more!!!
Can any a you guys do grade 8 math? How embarassing...
Delete300 pounds of ice will equal 300 pounds of water. The density is different - which means that the water will occupy a slightly smaller volume (about 10% less, I think) but the weight will remain the same.
ReplyDeleteA cubic foot of water weighs about 62 pounds, and a cubic foot of ice weighs around 57 pounds.
ReplyDeleteIf that chunk of ice is 12 cubic feet, then the guy is carrying around 684 pounds on his back. That seems unlikely.
This article is called, "Making Ice in Mississippi" and a few paragraphs down the article says that most commercial ice blocks weighed 300 pounds.

I'm going to go with explainst and say 300 pounds it is.
And it does look like the block is a bit wider than a foot, and less then five feet tall. So it works out.
Cool post. :)
But wait, there's more.
DeleteThis video shows a modern plant making ice in India, and when the block are slid from the molds they look quite close to the size of block the gent in the photo is holding.

And the 300 pounds of ice will be around 36 gallons of really cold water once melted.
ReplyDeleteIce, ice baby.
I think Jess’s volume estimate on that pic has to be off, or I pooched the math. And I think Jess is pretty close.
ReplyDeleteDamned if I can find my error though...😡
Conversion factors..... yuk. One or the other, but don't mix them. Airplanes turn into gliders when you convert.... Not a happy day.
DeleteI worked fora man who owned an Ice Block Plant in 1985. That looks to be the standard size block, like we made. They were roughly 300 pounds.
ReplyDeleteCan you ask what the dimensions are, B? I This is gonna bug me until I figure it out...
