For (KTT)P and (KST)P the preferred average values are 0.028 GPaK 1 and 0.019 GPaK 1 for β-(Mg,Fe) 2 SiO 4 and 0.027 GPaK 1 and 0.017 ... I Jackson,SM Rigden - 《Physics of the Earth & Planetary Interiors》 被引量: 319发表: 1996年 Correction to "Unified analyses for P-V-...
Using the equation for Mass Ratio, what is the mass ratio of a rocket that weighs 2,500,000 pounds fully fuelled, and 120,000 pounds empty? Answer and Explanation: Mass ratio= Mf/Me, Where Mf =Weight of fully fueled Rocket...
steps on the accelerator or applies brakes on a car, the speed of the car increases or decreases and the direction of the car changes. in physics, these changes in velocity or directional magnitude of a moving object are represented by acceleration. table of content what is average ...
He found that sound fills a reverberant room in such a way that the average energy per unit volume (i.e., the energy density) in any region is nearly the same as in any other region. The amount of reverberation depends on how much sound is absorbed by the walls in each reflection ...
Both lumped and distributed models have been hypothesized for these circuits; however, because of the flip–flop circuits, high operating speed distributed models seem more reasonable. The voltage v across the line and current i flowing through it, are functions of the neutral equation and obey ...

indicating that the average of the direct stresses, called the mechanical pressure, is equal to the thermodynamic pressure at all times whether there is motion or not. Substituting (2.11.8) into the momentum equation (2.3.12) and assuming that the variations in the inertial forces due to chang...
The numerical integration of eqns [1] and [2] is DNS; for LES eqns [1] and [2] need to be spatially filtered. The volume-filtered Navier–Stokes equations are derived by first decomposing all dependent variables, e.g., ui, into a volume average, u˜i, and a subgrid-scale (SGS)...
μ3(W0) is the reciprocal of the geometrical average of the error covariance matrix eigenvalues for the least square estimate. In general, if the estimation accuracy of system “1” is higher than that of system “2”, it means (43)W01−1≤W02−1 t implies (44)W01≥W02 ...
