Note on the hygroscopic equilibrium of cottonseed and cottonseed products
Journal of the American Oil Chemists' Society, 1948Summary and ConclusionsThe hygroscopic equilibrium of a sample of the Stoneville 2B variety of cottonseed and its derived products has been determined over the relative humidity range of 11 to 93%. In a previous publication (1) the hygroscopic equilibrium of a sample of the D and PL variety of cottonseed was determined over the range of 31 to 93 ...

We demonstrate that the equilibrium hygroscopic response of an aerosol droplet and the kinetics of water condensation and evaporation can be retrieved with high accuracy, even close to saturation, through comparative measurements of probe and sample aerosol droplets.

Experimental study of hygroscopic equilibrium and thermodynamic properties of sewage sludge
Applied Thermal Engineering, 2018Abstract A good knowledge of the hygroscopic behavior of sewage sludge is one of the keys to a better perception of the subsequent management of Sewage sludge such as drying, storage or other valorization processes. The present work aims to determine, experimentally, the sorption isotherms of sewage sludge generated at the wastewater treatment plant ...

Hygroscopic equilibrium of cottonseed
Journal of the American Oil Chemists' Society, 1947Summary and ConclusionAn investigation has been made of the hygroscopic equilibrium of cottonseed over a range of 31% to 93% relative humidity. From 31% to 71% relative humidity the moisture content of cottonseed increased linearly from 6.03% to 10.27%. From 71% to 93% relative humidity the moisture content increased rapidly from 10.27% to 22.19%. When

30—HEAT AND MOISTURE EXCHANGE IN WOOL BEDS: EQUILIBRIUM THEORY IN THE HYGROSCOPIC RANGE
The Journal of The Textile Institute, 1972Cassie's theory of propagation of heat and moisture changes in beds of wool fibres is re-examined by means of the method of characteristics. Substantial differences result in the predictions of the theory by treating the coefficients of the pertinent differential equations as functions of the dependent variables rather than as constants.

Theoretical analysis shows that when water activity is larger than its threshold value and the dry radius of a particle is larger than 0.005 μm, the deviation of curvature correction from unity can be accurately represented by the product of two terms, with one term strongly depending upon water activity and the other depending upon dry radius ...

AbstractThe hygroscopic behavior of microcapsules of antioxidant extract of defatted passion fruit seed, produced using spray drying technique, was analyzed at 20 and 40 °C by the static method with saturated saline solutions. The isosteric heat of sorption of the microcapsules, concentration of phenolic compounds and piceatannol, and the antioxidant ...

Abstract This paper proposes a V-shaped cone model to modify the Kelvin equation and thus obtaining an accurate connection between the effective aperture of hygroscopic material and its governing factors. A dimensional equation of equilibrium moisture content is presented based on the modified Kelvin equation.
