## How Big is a One Ton Block of Ice.

I thought this would be an easy look up on the web, but nothing. Figured weight of one gallon of water and the cubic inches, rounded up to allow for expansion. Then I looked up Block Ice, got a much lower number. I want this for a demostration on a Chiller.

8 LBs/Gal
2000/8=250 Gal
I believe one Gal is 231 In3, which would equal 57750 In3 or 33.42 Ft3
Now I dont know the expansion factor for ice, but the temp would make some difference with the expansion factor.

What do I win???? Huh!

Are you sure ? I thought that the specific density of Ice was .97.

Red gauge oil is like .825 or something like that and I know Ice is more dense that Gauge oil.

OK, I am gonna go look it up the old fassioned way, in a book, I'll be Back !

The density of ice at 0 C is approximately .97 g/cc.

Oops,
My bad. Specific Gravity (not density) of pure water is 1.00.
the Specific Gravity of Ice is .92

From the Pocket Reference, ya know that little black book !

Ok

Hey, I was close, and I did it long hand/manualy.
Why is this such an important question any way?

Water expands 9% when frozen.

Any combination of 35 cubic feet.

1 cubic foot of water is 7.48 gallons. 1 gallon is 8.33 lbs...

12. a cubic foot of water is about 62.4 pounds, ice expands by about 10%

2000/62.4 x1.1 = 35.26 cubic feet, 39.3"x39.3"x39.3"

it is definitely bigger than a 1 ton window shaker

13. ... but, what would weigh more, 1 ton of ice or one ton of refrigerant?
