A statistical mechanical formula is developed for the bulk viscosity of molecular liquids. It is expressed in terms of the self-diffusion coefficient of the liquid, intermolecular forces, and the site-site pair correlation functions. The density and temperature dependence of the bulk viscosity of ...
scientifically defined as its mass per volume. It can also be thought of as how compacted or compressed a substance is. When calculating a density from a mass and volume figure, it's important to remember that density can be affected by pressure and temperature, particularly where gases are ...
For an infinitely thin reaction layer (in the limit of infinite activation energy) we may solve the stretchless one-dimensional equations for the fuel mass fraction Y˜ℱ0 (s) and the temperature T˜0 (s) from Eq. (29) in the preheat zone, fixing sb = 0 to the ...
The method and performance of the temperature dependent subgroup formulation based on the concept of number density adjustment are presented for the application to the direct whole core calculation of power reactors that involves substantial thermal feedback. The number density of each resonant nuclide ...

Experimental results from four recent research reports on the determination of the density/temperature relationship of Standard Mean Ocean Water (SMOW) under a pressure of 101 325 Pa are analysed and a new formula is recommended for metrological applications. This paper determines the formulae of den...
At first glance, it appears that the correlation between density and temperature is low. However, given that the vast majority ofsewage sludgeincineration plantsoperate at temperatures ranging from 700 to 1200°C, it is reasonable to focus specifically on these results. With the exceptions of the...
Explicit expressions, which determine the boundaries of the regions containing temperature zeros of the partition function of the two-dimensional Ising model on an anisotropic triangular lattice, are obtained, along with a general formula for the density of zeros valid everywhere in regions containing ...
DETERMINATION of moist air properties from 0 to 100 掳C based on Tetens' relationship of temperature and vapor pressure and the psychrometric equation is presented. The resulting algorithms can easily be solved on a hand calculator or wr... A Weiss - 《Transactions of the Asae American Society...
5.5 The density matrix and the partition function of a system of free particles Suppose that the given system, which is composed of N indistinguishable, noninteracting particles confined to a cubical box of volume V, is a member of a canonical ensemble characterized by the temperature parameter ...
