22 April, 2002Weather Cloudy, Very windy, High 28, Low 10 Marge’s snow and ice competition continues! Marge Porter, a TEA teacher who worked with Dr. Jeffries did an ice thickness competition through her journals. Since we have less than a week left, ice thickness prediction contest is not possible. Instead, I’d like to do heat flux calculations. With raw data provided below, calculate snow density, thermal conductivity, temperature gradient, and conductive heat flux, and provide all of their units. The first person that e-mails me the correct answers by Thursday will receive a Poker Flat t-shirt. In your e-mail, please include your t-shirt size as well. For assistance, review the following topics: Snow density Thermal conductivity Temperature gradient Conductive heat flux Conductive heat flux, cont. GOOD LUCK! Find snow density, thermal conductivity, temperature gradient, conductive heat flux and their units. Mass 82.6 grams Snow depth (for density) 15.0 cm Surface temperature -5.3 ‘C Base temperature -1.5 ‘C Snow depth 0.16 meters __________________________________________________ Do You Yahoo!? Yahoo!
