For dry, uncompacted snow? The question came up during the recent cold snap in British Columbia, and as I was building snow piles on top of my huddled-together-containers. How much is enough? So far, I have come across the following "answers", applicable to dry snow with about 10% volume water: 1. Ten inches of fresh snow with a density of 0.07 inches, seven percent water, is approximately equal to a six-inch-layer of fiberglass insulation with an insulation R-value of R-18. 2. One inch of snow has an R-value of 1. Any thoughts on this?
Now this is a really cool (ugh, bad pun! Sorry) topic. What equations, etc. have you located for this? Reason I am interested, is that I teach chemistry and could see a really unique lab coming out of this.....
No equations. Just quotes from "not peer reviewed" websites. I can't find any "official" figure any where.
