Assuming that the snow is of the "heavy" 10: 1 variety, for which 10 inches of snow will melt to produce 1 inch of water equivalent, determine: (a) the total mass of snow which must be melted per hour (in lbm and in kg). use the volume of water formed and the water density or specific volume (b) the total energy (heat) requirement needed to melt this snow (in btu/h and in kw). the heat of fusion (freezing/melting) for water is approximately 334 kj/kg or 144 btu/lbm. (c) "they say" that the biggest challenge to the snowmelt system is not high rates of snow, but rather very windy conditions. in this case, there is a significant additional rate of heat loss due to convection. assume the following conditions for a very windy day: surface temperature = 32°f, air temperature = 20°f, h = 150 w/m2k what would be the rate of heat loss due to convection for this situation (in btu/h and in kw)? so are "they" correct?
