    recommend a good corrosion lab

    Thank you Ed. I already had hghouston do some preliminary work and got good results. I can see though from this website that these guys specialize in salt water. Perhaps I will try them next because we have more testing to do. Thank you, Mark

    recommend a good corrosion lab

    Gentlemen: We are a maker of a sporting goods product that has recently wound up in a salt water environment. It is a small reel that winds up cable as an alternative to laces on footwear. After prolonged exposure, the gears are seizing up. We have all kinds of materials present, stainless...

    Energy to melt snow

    Thank you all. I'm not sure how TD2K got 113MMBTU/lb? Using 144BTU/lb for heat of fusion and 500,000lbs of snow, isn't the worst case 72MM? I've still got an "expert" saying much less than that... Interesting from 25362 on residence time...

    Energy to melt snow

    Thank you TD2K: I think you are correct. The next thing I guess is determining the fraction of water in various snow conditions? Someone told me then that since there is a fraction of water in the snow then some is just sensible heat of water from initial temp to 60F?

    Energy to melt snow

    Thank you prex. Here are the numbers. We have 250tons/hour of snow being dumped into 2250 gallons of water that is 60 degrees F. Most often this would be done as snow is falling so perhaps air temperature of 15 to 32 degrees F. The density of the snow being blown into the tank will range from...

    Energy to melt snow

    We are working on a melting system for melting snow (250 tons/hr) and trying to calculate the energy required. We are depositing it in heated water. One system on the market claims an energy requirement which is less than what you would expect from a pure heat of fusion for ice calculation...
