Show as well. To simplify the calculations, a combination of cones must be used so that for each cone imprint diameter, snow strength ( hardness) can be expressed as a function of a number of varying cone angles and weights, for example, by using cone angles Of 60° and 32°( displacement volume is doubled here) and cone weights of 8, 40. 200, and 1000 g. The natural slope angle for loose snow was determined by piling to a height of about one meter. The results of a series of observations, calculating an average of 10 measurements, are given in Table 6. T a b l e 6 Natural Slope Angle of Loose Snow ( Angle0) Snow From To Average Fluffy, falling apart on pouring 48 53 50 Fine granular 47 52 48.5 Granular ( grains 1- 2 mm) 41 44 42 Coarse granular ( grains 4- 5 mm) 37 41 39 These observations show that the larger the snow grains, the smaller the natural slope angle. - 30- |
