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...
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 ...
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...
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...
A critical review of the existing literature on the pressure exerted by growing crystals in porous materials reveals that a number of different equations are in use. A derivation of an equation for the crystallization pressure based on the chemical potentials of the loaded and the unloaded faces ...
3.2. An Ideal RO-PRO Hybridized Process: Thermodynamic Approaches 3.2.1. A Fundamental Relationship between the Pressure and Specific Energy Investigating the relationship between the pressure and specific energy (SE) is worthwhile because the derivation steps of this relation comprise the theoretical bac...
The overburden pressure is caused by the vertical downward pressure exerted by rocks in the upper strata. Lithostatic pressure is the lateral pressure exerted by rocks in the surrounding strata. Due to the presence of pores in the rock, the fluid in the pores provides pore pressure. Fluid colu...
This causes a change in pressure exerted by the fluid on either side of the particle and leads to a net force. It has been observed in saltation of sand grains [18] and in blood vessels [19]. The Magnus lift force is a similar effect arising because of a relative rotation of a ...
To study the phenomenon of large deformation and the failure of roadways under dynamic pressure, this paper takes the 10607 gas drainage roadway as the research object and presents the results of a theoretical derivation of equations for the boundary of the plastic zone of a dynamic pressure roadw...
