The (gas + liquid) critical temperature of a number of ethers, esters, and ketones are reported. These values, together with values reported by Quadri and Kudchadker, and Ambrose and co-workers provide a fully extended data set for the development of correlations for predicting the critical ...
The nearer a gas is to its critical temperature the more it departs, in general, from the ideal gas behaviour. A vapour below the critical temperature behaves only very approximately as a perfect gas. The value of the s.v.p. at the critical temperature, i.e. the value of the pressure...
It is well known that the coefficient of discharge of the flow in the nozzle is a single function of Reynolds number. The purpose of the present study is to investigate the effect of unsteady downstream condition on hydrogen gas flow through a sonic nozzle, numerically. Navier-Stokes equations...
the finite number of Bosons and the interaction scale as N − 1 3 and N 1 6 , respectively. 6,7 Note that the shape of the trapping potential plays a decisive role for the critical temperature, as we have recently shown with a dilute gas of hydrogen atoms in a Ioffe trap. 8...
FLAME ARRESTER FOR THE SAFER USE OF HYDROGEN AS A LIFTING GAS IN AIRSHIPS An airship comprises an envelope accommodating hydrogen further comprising a flame arrester arrangement distributed along the envelope. The flame arrester arrangement comprises a plurality of cells made of mesh panels. The cel...
A quantum mechanical model requiring only strong quantum interaction for a charged particle gas estimates the superconducting transition temperature for wide-ranging states of matter. A general equation is derived which estimates the critical temperature T c the energy gap, and the coherence length for...
1, indicating the reduction of this degree of freedom upon confinement and slowing down of translative vibrational motion. The suppression of this low energy translative vibrational motion of confined salol molecules must be due to strong hydrogen bond interactions between salol molecules and the ...
. These models, however, do not account for the variability of temperature, land lithology, and the effect of continental configurations on climatic conditions, as well as their implications in terms of vegetation and associated mycorrhizal partners. To overcome these limitations, Roelandt et al.42...
Continued sonication appeared to accelerate the release of hydrogen from sodium borohydride but not the release of carbon dioxide from acetonedicarboxylic acid. Measured thresholds vary surprisingly little with temperature, indicating that the barrier to nucleation is primarily entropic rather than energetic....
