Particle-Size Distribution of Pulverized Snow

P2.5 Observations of Snow Particle Size Distribution with 2-d Video Disdrometer and Polarimetric Radar

1. INTRODUCTION Across much of the United States, and in many parts of the world, winter precipitation can come in many forms. It can range from all-liquid rain, to partially frozen particles, and completely frozen particles such as ice pellets or snow. The results of winter precipitation, then, are highly dependent on what type of precipitation falls. If rain falls into subfreezing environment...

Dynamic Evolution of Droplet/Particle Size Distribution in Suspension Polymerization of Styrene

Effect of Particle Size Distribution and Chemical Composition on Properties of Magnesia Chromite Bricks

The present study was undertaken to improve the quality and increase the life time of magnesia-chromite refractory bricks used in the copper and lead industries. The results show that a decrease in the amount of large chromite particles in the formulation improves the thermomechanical properties and also reduces the slag penetration in the bricks. In addition it was also observed that the use o...

investigation of models for describing soil particle size distribution

in the present study, five log-normal models, normal model (n), and two four- parameter models namely gompertz (g) and fredlund (fr) were tested on 71 psd data from 10 soil textural classes. the jaky (j) and fr models had the smallest and largest r2 values for all of the soils, respectively. the results of comparing the n and simple log-normal (sl) models showed that the accuracy of the n model...
