Ok. I rarely come here, but a worker throw out this problem and I have a answer But i want to make sure it matches up.. the question is.... how many inches of snow would it take to fill 10 gallons with water

Give us your answer

Do you mean cubic-inches?

>A 30-yr climatology of the snow-to-liquid-equivalent ratio (SLR) using the National Weather Service (NWS) Cooperative Summary of the Day (COOP) data is presented. Descriptive statistics are presented for 96 NWS county warning areas (CWAs), along with a discussion of selected histograms of interest. The results of the climatology indicate that a mean SLR value of 13 appears more appropriate for much of the country rather than the often-assumed value of 10, although considerable spatial variation in the mean exists

tl;dr 13" of new snow melts to 1" of water.

Thats one inch of water. I am asking what would be the liquid measure. IE gallons. 5 gallons of snow equal to 1/2 gallon of water. But i wanna know how many inches that would be to fill up 10 gallons of water..

you'll need to specify a surface area before we can give you an answer to that.

I just need to know the amount of snow needed in inches for 10 gallons

>> No.5249370

>>5249356
23.4 inches

>> No.5249377

>http://en.wikipedia.org/wiki/Snow#Density
>Once the snow is on the ground, it will settle under its own weight (largely due to differential evaporation) until its density is approximately 30% of water.
I'll go with this.

m/Vs ~= 0.3m/Vw
mVw ~= 0.3mVs
Vw ~= 0.3Vs
Vw/0.3 ~= Vs

10/0.3 ~= 33.333...

So 10 gallons of water is aprox. equivalent to 33.333 gallons of snow.
Someone else can do the conversion to cubic inches. I don't feel like looking up the conversion factors.

That's 1/10 of a gallon...

>> No.5249402

Depends on snow water equivalent which varies from place to place. You can stop being a bunch of retarded tryhards any day now, /sci/.

In this question it doesn't matter where it falls. just how many inches of snow would it take to create 10 gallons of water.

It's actually 231. I pulled 23.4 out of my ass, and by pure coincidence it was almost 1/10 gal.


And OP, are you talking about cubic inches or inches? Get it fucking right, the difference matters. Asking for just inches is nonsensical.

I was trying to make the problem easy , But it seems with you guy you need all information. So here it is... How many inches of snow would be needed to get 86,000 gallons, in a area of 25yards by 75 ft.......

All those imperial units. I'm not even going to touch that one. Goodday.

231 cubic inches in a gallon

snow is about 1/10 as dense as water (that varies, by the way)

one square foot is 144 inches

you want 2310 cubic inches of water

10*(2310/144)
