The total mass of the atmosphere varies mainly from changes in water vapor loading; the former is proportional to global mean surface pressure and the water vapor component is computed directly from specific humidity and precipitable water using the 40-yr European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analyses (ERA-40). Their difference, the mass of the dry atmosphere, is estimat...

Response data were collected for a carbon black-polymer composite electronic nose array during exposure to homologous series of alkanes and alcohols. The mean response intensity of the electronic nose detectors and the response intensity of the most strongly driven set of electronic nose detectors were essentially constant for members of a chemically homologous odorant series when the concentra...

The vapor pressure of rubidium was determined in the neighborhood of 330 K from measurements of optical absorption of the resonance lines. A narrow-line source was used and a full analysis of the line profiles was done. Measurements of resonance-broadening depolarization give another check on the Rb vapor pressure in the 430-K range, assuming that theoretical cross section is correct. The resul...

The effects of moisture on the flow properties, tensile strength, Heckel plot (particle rearrangement, yield pressure), energies involved in compaction (gross, plastic, and elastic energies), and elastic recovery are reviewed. he identification and quantification of the numerous parameters that affect the compaction process are vital for product uniformity. For example, moisture adsorption play...

An analytical model is developed for the startup transient of asymmetrical flat-plate and diskshaped heat pipes. The model solves the proper transient heat conduction equations for the heat pipe wall and liquid-wick regions. A quasi-steady state, pseudo three-dimensional approximation is used for the vapor transi’ent behavior. The heat transfer within the wall and liquid-wick regions is coupled...

An in-depth integral analysis revealing various physical aspects of an asymmetrical flat plate heat pipe is presented in this work. The resulting psuedo-three-dimensional vapor phase Row field is bifurcated on the X-J’ plane due to the asymmetrical nature of the heat source and sinks. The analytical results for the shifted vapor velocity profiles on the x-y plane, the overall axial pressure dis...

Anomalous liquid behavior is viewed as a result of an increase in surface tension in isolated capillaries. Using a derived prime equation for this change several phenomena are treated including the strength of liquid bridges between solids, the lowering of vapor pressure, increased solubility, and adsorption-desorption hysteresis. Using experimental data available on thestrengthofliquid bridges...

This work presents a set of three simple and explicit equations as a function of temperature, pressure, and mass fraction for calculation of the entropy of the ammonia-water mixture in saturated and super heated conditions. They are intended for use in the optimization and second law efficiency of absorption processes. The equations are constructed by the least square method for curve fitting u...
