To understand the clustering of galaxies under the influence of gravitational force, cosmic energy equation is of great help. We use cosmic energy equation for extended structures (galaxies with halos) to analyse the gravitational galaxy clustering in different ways. We try to understand the ...
As we will see in the examples below, that force could be the attractive gravitational force as defined by Newton's law of universal gravitation, it could be the tension in a rope, and it could be the force of something pushing inward, like the wall in an amusement park ride....
Just like flow through a pipe, the frictional force relies on the flow’s laminarity and certain gas characteristics. To account for a wider range of flow regime, the Ergun equations is used as it can handle both laminar and turbulent flows. The Ergun equation is shown in Eq. (5). (5...
We can further simplify the equation by taking h2 = 0 (we can always choose some height to be zero, just as we often have done for other situations involving the gravitational force, and take all other heights to be relative to this). In that case, we get P2=P1+ρgh1P2=P1+ρgh1...
In this equation,ρ is the density of the liquid and g is the gravitational acceleration. (3.19)πE=−ρgh22 Finally, by substituting for the interfacial tension from the modified Young's equation (Eqn (3.12)) into the work of adhesion (Eqn (3.20)) for a solid–liquid system, the ...
(1)and(2)are two forms of the Bernoulli Equation for a steady state in-compressible flow. If we assume that the gravitational body force is negligible - the elevation is small - then the Bernoulli equation can be modified to p = p1+ ρ v12/ 2 ...
