The phrase "ascent velocity" is correct and usable in written English.
It can be used in contexts related to physics, aviation, or any situation where the speed of an upward movement is being discussed.
Example: "The rocket's ascent velocity increased significantly as it approached the stratosphere."
Alternatives: "climb rate" or "rise speed".
The increase in pore pressure can enhance the gas ascent velocity and, consequently, the 222Rn concentration.
Because gas ascent velocity generally is slow in the study area, the 222Rn source must be located in shallow soils.
This increase in pore pressure can enhance the ascent velocity of 222Rn carrier gas as governed by Darcy's law.
In the present case, the ascent velocity of the liquid phase is 0.1 m/s (discharge rate = 87 m3/s, R c = 16 m).
When volatiles are not included in the magma, the magma ascent velocity decreases with time and the deformation decelerates, since the driving force, which is the pressure gradient, becomes weak with the magma ascent.
The cause of the nonequilibrium gas patterns at 21% of the points, indicating young gas of short elapsed time since 222Rn generation, was interpreted as high ascent velocity of 222Rn carrier gas.
This type of gas is young (i.e., not much time has elapsed after the generation of 222Rn atoms) and observed typically in fumarole gases with high ascent velocities (Koike et al. 2009, 2014).
Zone A includes a zone of high radon-222 concentration in soil gas, which suggests large gas ascent velocities caused by frequently induced strain along the Hinagu fault (Koike et al. 2014).
For these rising mechanisms, slug ascent velocities would be on the order of 2 30 m s−1 [ Harris and Ripepe, 2007; James et al., 2006, 2008], thus implying rise times spanning the 10 10 s range.
Additionally, observing the effects of injection pressure on the penetration characteristics of the two modes yielded insight into the duration of the rapid ascent of spherical velocity and the correlations between the spray front angle θ, oblique shock angle β, and spray tip Mach number M in the oblique shock.
Ascent to altitude leads to velocity and power improvements although the mechanisms that promote the benefit of this type of hypoxia with respect to the NH still require clarification.
