A simple approximate relation is derived for the temperature of the maximum occurring in the vapour-pressure lines of saturated solutions of a number of non-volatile substances of high melting point in a volatile solvent. The derivation is analogous to that for saturated solutions of one dissolved...
By introducing a simple quadratic function and using a sectional fitting method,the effect data range of current fast calculation formulae for R410Asaturatedthermal properties was extended to the critical region. 通过引入简单的二次函数并采用分段拟合的方法,将现有的制冷剂R410A饱和区物性快速计算公式的...
performed twice by utilizing the change of atmospheric pressure under a condition that the temperature is constant, to determine the measured value of the change of volume, thereby the saturated vapour pressure and the vapour pressure drop can be determined on the basis of the calculation formula....
7,11,12,17,18,19]). The most serious of the shortcomings [12] lies in the lack of control of water vapour pressure\(p_\textrm{w}\)(or RH) at the specimen surface, especially in the interior of the cup. Since there is a mass flux from the surface of the salt solution or desicc...
(m = 0.65, R2 = 0.67,p < 0.01; see Supplementary Fig.7). The calculation based on the kinetic fractionation coefficients of the smooth wind regime leads to an RHsea/d-excess distribution (Fig.4) with a similar slope as the observations, but is biased towards higher d-...
However, very limited information is available on the precision of the IWV determined by radiosondes. In this paper the methodology of the computation of IWV retrieved from radiosonde data is revised using the atmospheric profiles of pressure, relative humidity and temperature. The formulae to ...
In this section, we discuss the translation of this product into the zenith total delay and its gradients along the E-W and N-S directions, and subsequently, the calculation of the zenith hydrostatic delay, the zenith wet delay, and the water vapour amount. We also describe the approach to...
pressure at higher altitudes, while a pronounced low-pressure system developed at mid and low altitudes within the basin, establishing a meteorological context marked by upper-level divergence and lower-level convergence. Throughout the event, notable vertical uplift velocities were recorded across the ...
The coefficients of the series can be obtained from fluctuation formulae by performing grand canonical Monte Carlo (GC MC) simulations on both vapour and liquid sides. It was found that the main shortcoming of the method originates from the inaccurate calculation of the pressure on liquid side ...
