ORH_wxman Posted February 21, 2019 Share Posted February 21, 2019 A cubic yard of water weighs around 1700 pounds....so just adjust given your snow to water ratio if you want to get the weight of a cubic yard of snow. 2 Link to comment Share on other sites More sharing options...
Connecticut Appleman Posted February 21, 2019 Share Posted February 21, 2019 FWIW - water reaches a maximum density at approx 4 C or 40 F. The density of water decreases as you approach the freezing point. 2 Link to comment Share on other sites More sharing options...

The density of water decreases as you approach the freezing point. Yup...below 4C the water molecules start to arrange themselves in hexagonal arrangements in preparation for freezing at 0C. I’ve found you need to get the wetbulbs above that 3-4C mark to really start melting the snow in a torch. 1 Link to comment Share on other sites More sharing options...

Typhoon Tip Posted February 22, 2019 Share Posted February 22, 2019 1 hour ago, #NoPoles said: @CoastalWx @OceanStWx @dendrite Or any other math person. How do you calculate the weight of a cubic yard of snow? I googled a cubic foot of snow generically weighs 20lbs. How would you calculate for my area based on the water content of the storm that just fell? I dunno ... 170 lbs... figure 10:1 and go from there... If 1700 lb is a cubic yard of liquid water, that implies 1700/10:1, which is the thus (1700/10) X 1 = 170 But ...real life seldom resembles real numbers... If you "fill" snow into a yardXyardXyard bin... it's probably highly aerated and therefore, not really 10:1... more like 20 :1 or perhaps 15 ...or something less dense than 10:1 ... So you gotta kinda use your head. 1 Link to comment Share on other sites More sharing options...

MegaMike Posted February 22, 2019 Share Posted February 22, 2019 I think I see what she's asking for... The weight of water in lbs as a function of snow depth and or volume (length,width,height)... Density of water = 997 kg/m^3. Assuming a volume of 1 cubic yard: weight(depth) = ((997 kg/m^3)*[1 yard]^3*[(3 ft/yard)^3]*[(12 inch/ft)^3]* [( 2.54 cm/inch)^3]* [(1m/100cm)^3)])*2.20462 lb/kg == 1680 lb You can also change it to (assuming length/width/height is measured in yards): weight(length,width,height) = ((997 kg/m^3)*[length*width*height]*[(3 ft/yard)^3]*[(12 inch/ft)^3]* [( 2.54 cm/inch)^3]* [(1m/100cm)^3)])*2.20462 lb/kg Just be careful with the units. I made these two conversions assuming you measured a depth/length/width/height in yards. You'll have to exclude some terms if you utilize a different unit of measurement. edit: weight not wight... 1 Link to comment Share on other sites More sharing options...

ineedsnow Posted February 22, 2019 Share Posted February 22, 2019 We ice! A wintry mess is forecast across much of Southern New England. A brief burst of snow and sleet followed by a longer period of freezing rain, especially across the interior and away from the coastline. Greater concern is ice accretion on all surfaces beginning Saturday night into the first-half of Sunday. Hazardous travel impacts. At times, reductions to visibility. 1 Link to comment Share on other sites More sharing options...

MegaMike Posted February 22, 2019 Share Posted February 22, 2019 40 minutes ago, Ginx snewx said: Or use an already developed roof snow load calculator I thought she was looking for how the units canceled out and a simple function for the weight of snow/water on a flat plane. This is what I did. But, last point and I'll stop discussing this topic... If you're looking for the weight of snow/water on an incline/roof, you can take the weight of the snow *times* the cosine of theta (angle of the roof). So, weight.perp.roof(depth[inches],theta[degrees]) = (((997 kg/m^3)*[(SWE)^3]* [( 2.54 cm/inch)^3]* [(1m/100cm)^3)])*2.20462 lb/kg)*cos(theta) I'm sure the younger audience on this forum would find it helpful to see how the units cancel out.
