Moisture total

Numbers represent % of total moisture of ash-free freshly mined coal. 

The best indirect, but seldom used, method is to determine the total moisture separately in a Penfteld tube, determine the loss on ignition in air at 825—875°C, and report graphitic carbon as percent loss on ignition (100 — %moisture — %ash). It is desirable to use a platinum dish for ignition loss and it... 

Moisture Holding Capacity. The bed or equihbrium moisture is the amount of moisture retained after equihbration at 96—97% rh at 30°C (D1412) (18). Total moisture is determined by air drying, cmshing to smaller particle sizes and heating at 107°C to constant weight (D3302). 

Mass Transfer and Useful Capacity. The term useful capacity, also referred to earlier as breakthrough capacity, differs from the equihbrium capacity shown on Figures 9a and 9b. The useful capacity is a measure of the total moisture taken up by a packed bed of adsorbent at the point where moisture begins to appear in the effluent. Thus the drying process cycle must be stopped before the adsorbent is fully saturated. The portion of the bed that is not saturated to an equihbrium level is called the mass-transfer 2one. 

The propriety of using the moisture content of the whole food substance as the critical variable is, however, open to question because the moisture within a given food is not distributed uniformly. The total moisture content is a sum of the moisture contents of the various components, such as starch, pectin, protein, sugar, and cellulose. 

The principal factors which affect the breaking temperature are type of salad oil (cottonseed, corn, soybean, or other), proportion of oil, proportion of total moisture, and proportion of yolk. To a much lesser degree, the breaking temperature is also influenced by the mean particle size of the dispersed oil and the concentration of crystalloids in the water. 

Total moisture designates the sum total of the moisture content of the yolk, vinegar, and water added as such. 

By integrating Eq. (46) and applying the boundary conditions, the solution for the total moisture uptake limited by mass transport is found. In the solution shown in Eq. (47) the vapor pressures have been converted to relative humidities and it has been assumed that the partial pressure of water is much less than the total pressure. Under these conditions, Eq. (47) is the solution for mass transport resistance in spherical coordinates. As with transport in rectangular coordinates, the important variables are the partial pressures of the chamber and above the solid surface and the distance between the solid surface and chamber wall. 

To illustrate this more quantitatively, consider the hypothetical sucrose example discussed by Ahlneck and Zografi [80]. Assuming that all the sorbed water is taken up by the amorphous portion of material, 0.1% total moisture would correspond to approximately 20%, 10%, 4%, and 2% moisture content in the amorphous material, respectively, for 0.5%, 1%, 2.5%, and 5% of amorphous solid. The glass transition temperatures for the amorphous portions... 

In general, the system requires that wastes contain less than 5% total moisture and with a particle size less than 200 mesh. Wastes must be transported to a stationary HRD facility for treatment. The HRD flame reactor system cannot treat mercury-containing wastes. 

Total moisture content is determined on a separate 100 to 200g sample by distilling it in a 500ml flask with 200ml of dry CCU... 

Relation of Radon Concentration in the Atmosphere to Total Moisture Detention in Soil and Atmospheric Thermal Stability... 

C is the average monthly morning radon concentration in pCi./cu. meter computed from radon daughter measurements, S is the stability in °F./27 meters, and TMD is the total moisture detention in mm. The constants k and k and the correlation coefficients for the equations were obtained for all three variables and also separately for C vs. stability and C vs. TMD.

Average monthly morning radon concentration varied inversely with soil moisture content, expressed in terms of Thomthwaite s total moisture detention. The two variables were highly correlated, the squared correlation coefficient being 0.84. By relating radon concentration in air to both TMD and stability, the squared correlation coefficient increased to 0.89. An alternative mathematical relation, the logarithm of the radon concentration vs. TMD and stability, showed identical correlation. 

Solution For lincomycin, we observe —20.7 pg more H20 than expected, independent of the sample size. Excess HzO comes from the atmosphere when the port is opened to add solid. To determine moisture in unknowns, subtract this blank from the total moisture titrated. This procedure can generate very reproducible data.
