The modified power law has successfully been applied to describe temperature changes in the viscosity eta of water at normal and higher pressures.doi:10.1103/physrevb.50.777MATCZUK AKULAK LBOJARSKI C
Power-Law with 2 Parameters for the Viscosity of Normal and Supercooled Water Based on an analysis of the temperature dependence of activation energies, performed for the rotational diffusion of water molecules and for their reorientation in the proton conductivity process, the relation gamma = 1 +...
Ultrasonic Absorption in Normal- and Para-Hydrogen SEVERAL years ago it was found by one of us, together with P. Mariens 1 and L. Thys 2 , that the experimental values found for the ultrasonic absorption coefficient is much larger than the theoretical value computed by means of the equa.....
[translate] aSince the viscosity of air is much less than that of water, this term is safely ignored. 因为空气黏度比那是较少水,这个期限安全地被忽略。[translate]
2.1.1 Water content model of PEMFC A one-dimensional water transfer mechanism model was developed in this paper to study the water transport characteristics of a Nafion®NR211-based MEA (membrane electrode assembly) for PEMFC. As the site of electrochemical reaction, the catalytic layer is a ...
Blood is a liquid consists of plasma and particles, such as the red blood cells. The viscosity of blood thus depends on the viscosity of the plasma, in combination with the hematocrit. The viscosity of normal blood is about three times as great as the viscosity of water. When the ...
awhere F is the inverse cumulative normal distribution function for the confidence level of . We illustrate the EE and PFE of the example interest rate swap in Figure 5.6 and compare the values obtained with simple approximations resulting in good agreement. The exposure transformation created by ...
this temperature, initially the pressure effect is negative but at about 1,000 kg/cm2the viscosity relative to 1 atm. exhibits a minimum. Presumably at this pressure the structured regions occurring in water have been partially destroyed and the behaviour is more like that of a “normal” ...
Estimation of the normal boiling points of water and 1,2-dimethoxyethane through the viscosity–temperature dependence in the corresponding binary mixturesExcess properties calculated from literature values of experimental density and viscosity in N,N-dimethylacetamide + formamide binary mixtures at (298.15 ...
Infrared Spectra and Normal Vibrations of N,N-Dimethylformamide and N,N-Dimethylthioformamide The infrared spectra of N,N-dimethylformamide (DMF) and N,N-dimethylthioformamide (DMTF) have been investigated in the range 4000鈥 250 cm1. Assignment of t... G.,Durgaprasad,D.,... - 《Bulletin...
