in this work, experimental studies of internal friction coefficient and porosity of four high productive rice varieties in iran (nemat, neda, pajouhesh and pardis) have been presented. moisture content varied in four different ranges between 8 and 20%. the obtained results indicated that the internal friction coefficient decreased with increasing the moisture content from 8 to 11%, then decreas...

the water relations play a fundamental role in seed comprehension of biology. in order to describe the process of drying and the effect on water activity, which controls biological change in storage, a sound knowledge of the relationship between equilibrium moisture content (emc) and water activity/equilibrium relative humidity (erh) is essential. the relationship between the total moisture con...

Drying data for individual rice kernels and bulk samples selected from various tillers of a plant and from different maturity groups were experimentally obtained. The data showed that over 93% of the drying occurred within 24 h of exposure to air at 40° C and 60% relative humidity. Differences in the equilibrium moisture content and drying rate constant among kernels were observed. Equilibrium ...

This study was undertaken to evaluate the Physico-chemical properties of eight different types of biomass feedstock and their briquettes were studied among that some properties which are influence their storage and combustion properties like Equilibrium moisture content (EMC %) and Relative humidity (%). Equilibrium moisture content are found out by static equilibrium technique using aqueous gl...

We derive steady equilibria for lateral downslope moisture flow in an ide-alized thin closed layer as a solution to the 1D Richards' Equation. The equilibria are determined by two free parameters: the downslope flux and a boundary condition. Solutions exhibit a constant downslope flow speed and moisture content for the constant equilibrium flux, which is the product of the two. However where an...
