Preparation of Uniform Sand Specimens Using Stationary ...
Relative density is an important state parameter that influences the soil behavior. Preparation of sand specimens with uniform density is critical during large-scale laboratory testing in geotechnical engineering. In this study, the details of a stationary air pluviation device used to prepare uniform sand specimens in a large-size test chamber with dimensions equal to 900 mm × 900 mm × …

In Newtonian mechanics mass cannot disappear, it is assumed to be constant. To imagine why it is not a good idea to have variable mass, think that if mass could be created or destroyed, momentum would no longer be conserved, because in absence of a force, it will be accelerated: $frac{dv}{dt}=-frac{v}{m}frac{dm}{dt}$ thus a moving object would slow down as if a friction force …
