THE INCLUSION OF A SAND LAYER OVER THE SUBGRADE PROVIDES AN EFFECTIVE METHOD OF CHECKING CAPILLARY RISE OF MOISTURE FROM THE SUBGRADE TO THE PAVEMENT. THE THICKNESS OF THE SAND LAYER REQUIRED TO COMPLETELY CUT OFF CAPILLARY RISE OF MOISTURE CAN BE CALCULATED FROM A NUMBER OF FORMULAS. THESE FOR...
Assuming a constant electric conductivity (we also can use the empirical formula for electric conductivity as given in Table 2 to find a more accurate estimation of the whole-capillary temperature rise), the temperature elevation, ΔT, of the whole capillary is given by (157)ΔT=σ(EnomR)...
These factors have been taken into account to develop the empirical equation for capillary rise simulation. The model parameters for Songnen Plain were derived by Levenberg-Marquardt and global optimization calculating method. The modeled capillary rise has a good agreement with the observed data (r2...
The model parameters for Songnen Plain were derived by Levenberg鈥揗arquardt and global optimization calculating method. The modeled capillary rise has a good agreement with the observed data (=0.875). With the simulation model, the critical water table depth was identified as 2.5m, indicating ...
The rise of water by capillarity is a well-known and important factor in monument weathering, especially in the case of historic brick buildings where the waterfront reaches considerable heights. The capillary rise can be simply calculated by means of the Laplace formula, isolating h from the ...
Will water rise in the tube? Why or why not? Explain Poiseuille's formula for the volume of liquid flowing through a capillary tube. Describe the capillary rise method for finding the surface tension of a liquid. How does the height to which water is lifted in a capillary tube ...
This invention relates to an apparatus and method for connecting the end of a tubular body, particularly a chromatographic capillary tube, to a detection or injection device fitting. Known apparatus and methods for making such a connection suffer from the drawbacks of requiring a considerable amount...
A close-packed, well-ordered monolayer can be formed on a freshly cleaved muscovite mica surface by allowing hydrolyzed octadecyltriethoxysilane to self-assemble from a dilute hydrocarbon solution. The alkyl chains in the monolayer deposited by this method appear to be in a pseudocrystalline environmen...
discrepancies of the simulated and measured temperatures in Fig.1a was because the simulated temperature is actually the average temperature of the porous wick with e-liquids inside due to the lumped parameter method used in the main part of the model, while the measured temperature is the surface...
This single TRP-PCR/fragment analysis method can be used for both carrier and newborn screening as a first-tier test. By using this algorithm, the number of samples requiring Southern analysis is reduced by 98%. Of those samples reflexed to further testing, approximately 5 to 7% will be ...
