Large water-hammer pressure for column separation in pipelines [PDF]

open access: yes, 1991
Water-hammer pressures in a pipeline due to the collapse of a vapor cavity adjacent to a valve are investigated. A water-hammer event is initiated by the closure of a valve in a simple reservoir-pipeline-valve system.

Variation of Relative Humidity as Seen through Linking Water Vapor to Air Temperature: An Assessment of Interannual Variations in the Near-Surface Atmosphere

open access: yesAtmosphere, 2022
It has generally been regarded that, in the warming climate, atmospheric water vapor may increase due to the enhancement in surface evaporation, which is expected from the Clausius–Clapeyron (C–C) equation, along with the assumption that relative ...

New convenient vapor pressure-temperature correlation for some aliphatic hydrocarbons

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2013
New empirical equations for correlating temperature dependence of vapor pressure for C6-C20 aliphatic hydrocarbons are proposed: ln(VP) = k1·T/(k2+T) where, VP – vapor pressure, T – temperature, k1 – asymptotic maximum vapor pressure, and k2 ...

Continuous phase transition and negative specific heat in finite nuclei [PDF]

open access: yes, 2006
The liquid-gas phase transition in finite nuclei is studied in a heated liquid-drop model where the nuclear drop is assumed to be in thermodynamic equilibrium with its own evaporated nucleonic vapor conserving the total baryon number and isospin of the ...

Experimental study of ultracold neutron production in pressurized superfluid helium [PDF]

open access: yes, 2015
We have investigated experimentally the pressure dependence of the production of ultracold neutrons (UCN) in superfluid helium in the range from saturated vapor pressure to 20bar.

Loading a vapor cell magneto-optic trap using light-induced atom desorption [PDF]

open access: yes, 2000
Low intensity white light was used to increase the loading rate of $^{87}$Rb atoms into a vapor cell magneto-optic trap by inducing non-thermal desorption of Rb atoms from the stainless steel walls of the vapor cell.
