The given equation represents the combination of classical equations with the statistical distribution of corresponding parameters and the properties of microscopic objects may be interpreted on the ontological basis as it corresponds to our sensual knowledge. It will be shown now that also the main ...
Find an equation that describes how distance (x) changes with respect to time (t). Differentiate the formula with respect to time. Let dx/dt = instantaneous velocity. Input the desired time into the differentiated formula. The result is the instantaneous speed at time t. How long does it ...
We invert the Jeans equation to obtain the velocity-anisotropy profiles of cluster members. With the mass-density and velocity-anisotropy profiles we then obtain the first determination of a cluster pseudo-phase-space density profile. Results: The kinematics and lensing determinations of the cluster ...
Transfer matrix modeling of hyperbolic and parabolic ducts with incompressible mean flow A general differential equation for the propagation of sound in a variable area duct or nozzle carrying incompressible mean flow (of low Mach number) is de... V Easwaran,ML Munjal - 《Journal of the Acoustica...
In the mass conservation equation for component i, the expression for the diffusion term on its right-hand side will change when the convection velocity on its left-hand side changes. In turbulent flow, there could be no diffusion terms, or a turbulent diffusion term only, or both the ...
Another route to follow in order to obtain equation (1.66) is to start out with the macroscopic instantaneous momentum equation for an incompressible fluid given by Hsu and Cheng (1990): (1.67)ρ{∂∂t(ϕ〈u〉i)+∇⋅(ϕ〈u〉i〈u〉i)}=–∇[ϕ(〈p〉i)]+μ∇2(ϕ〈...
where ut is a measure of the turbulent velocity fluctuation, It is a measure of the turbulent length scale and θ is the angle of the jet with the liquid free-surface (fig. 5-1(A)). In dimensionless terms, equation (6-2) becomes : (6-4)Veμw3*gσ2*ρw=F2Mo;utμw3*gσ2*...

The paper is concerned with the velocity boundary layer when the fluid properties are uniform and mass is transferred in either direction through the wall boundary. The "similar" form of the velocity equation is used to examine the asymptotic behaviour of boundary-layer functions for large mass-...
relates force, mass and acceleration in the equation force (F) equals mass (m) times acceleration (a), written as F = ma. Another formula, acceleration (a) equals change in velocity (Δv) divided by change in time (Δt), calculates the rate of change in velocity over time. This ...
