The drag exerted by the gas on the liquid complements the frictional force at the pipe wall. Sign in to download full-size image Figure 4.19. Frictional component of pressure gradient for the results shown in Figure 4.18 It is, in principle, possible to split the liquid holdup, measured at...
Asheesh Kumar, in Challenges and Recent Advances in Sustainable Oil and Gas Recovery and Transportation, 2023 4.6.3 Disjoining pressure The pressure exerted by the nanoparticles on the rock surface is known as disjoining pressure, which is responsible for Brownian motion, injection pressure, and ...
(Picture by Matthieumarechal CC BY-SA 3.0). The Clausius-Clapeyron equation is a derivation of this formula. It describes the relationship between the vapor pressure and the temperature of a liquid. It's accurate for the phase transition between liquid and gas (vaporization) or solid and gas ...
Atmospheric pressure is the force exerted by the weight of air in the Earth's atmosphere. This pressure can affect the weight of objects on Earth by either increasing or decreasing their weight, depending on the altitude and the density of the air.What is the difference between pressure caused...
Furthermore, use of this technology usually was limited to the injection of gas into the vitreous near the end of the surgery. By contrast, the noninvasive and remarkably accurate IOP monitor that we report could provide an additional tool for vitreoretinal surgeons to evaluate and improve their...
I point you the derivation and calculations leading to and in 4.48 of the paper (where the cancellations are shown for all to see), and the similar results for each case considered. Explicit calculations and analysis are supposed to be trumped by your opinion? I will certainly have nothing ...
Thus we do not expect that Correns and Steinborn’s experiments were perturbed by the formation of either of these phases. The values of Miers (1904) that were taken for Doelters handbook deviate somewhat from ours. We thank Prof. Ulich (Aachen) for his help in the derivation (see also...

The geometry used for the derivation of the radiation patterns of a rigid piston mounted on a flat, rigid baffle of infinite extent. Ds is an infinitesimal piston area whose vibration produces sound in the field point B. The total acoustic pressure P(r,θ,t) at B is found by integrating...
The coal seam dip angle exerted the greatest influence, and a new hydraulic fracturing construction procedure is proposed: the pump pressure should be gradually increased from the minimum initiation pressure according to the fracture initiation pressure gradient required by each failure mode. A field ...
