Swelling Bulk Density and its Application in Arya and Paris Model for Soil Moisture Curve Prediction

Nondestructive sensing of bulk density and moisture content in shelled peanuts from microwave permittivity measurements

Dielectric-based methods were used to determine nondestructively and simultaneously bulk density and moisture content in shelled peanuts from measurement of their relative complex permittivity at microwave frequencies (7–12 GHz) and 24 C. The first method is based on direct relationships between the two components of the relative complex permittivity (dielectric constant and dielectric loss fac...

Estimating bulk density of compacted grains in storage bins and modifications of Janssen's load equations as affected by bulk density

Janssen created a classical theory based on calculus to estimate static vertical and horizontal pressures within beds of bulk corn. Even today, his equations are widely used to calculate static loadings imposed by granular materials stored in bins. Many standards such as American Concrete Institute (ACI) 313, American Society of Agricultural and Biological Engineers EP 433, German DIN 1055, Can...

A microwave method for on-line determination of bulk density and moisture content of particulate materials

A new method for simultaneous and independent on-line determination of bulk density and moisture content in particulate materials by measurements of the relative complex permittivity is proposed. The bulk density is determined, based on a representation in the complex plane of relative complex permittivity normalized to bulk density. For moisture content determination, a new density-independent...
