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 ...
Pressure caused by weight refers to the force exerted on a surface due to the weight of an object. On the other hand, pressure caused by molecules motion refers to the force exerted on a surface due to the motion and collision of molecules within a substance. While both types of pressure...
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...
Mixtures of different molecules are never ideal, but we can treat them as if they were to simplify our calculations. Let's use this vapor pressure equation in an exercise: What is the vapor pressure of a solution made by dissolving 100 grams of glucose (C6H12O6) in 500 grams of water?
Ulich (Aachen) for his help in the derivation (see also Ulich, Lehrbuch der Thermodynamik—Textbook of thermodymakics). Translation note: apparently this is an incorrect quote, Prof. Ulich was rather the author of Kurzes Lehrbuch der physikalischen Chemie (short textbook of physical chemistry)....
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 ...
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 ...
In this section, for a clear understanding, the fundamental models mathematically describing the energy-generating procedures in PRO will be elaborated with detailed derivation steps. 2.1. Water Flux and Power Density Now let us introduce mathematical notations and equations. The most fundamental and co...
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...
Research indicates that enhancing the confining pressure exerted on the fractured rock mass surrounding the roadway can lead to a substantial enhancement in the residual strength of the surrounding rock and an increase in the load-bearing capacity of the superficial rock mass within the roadway [31]...
