Rayleigh speed

We note that on the surface of the solid there can only exist shear waves the speed of propagation of these waves, called the Rayleigh speed cr, is typically cr 0.9Cs.

Since the conservation equations for a normal shock are represented by the Rayleigh and Fanno conditions, the final point must be on both lines and pass through the initial point. Since heat addition in a constant area duct cannot raise the velocity of the reacting fluid past the sonic speed, Fig. 1.8 represents the... 

Note that Eq. (5.5) is the equation of the Rayleigh line, which can also be derived without involving any equation of state. Since (p u )2 is always a positive value, it follows that if p2 > p, P2 > Pi and vice versa. Since the sound speed c can be written as... 

The Rayleigh wave speed of sound Cr is determined by the equation ... 

The first process is the deformation of droplets into an ellipsoid, until the droplet breaks up. The second process is A droplet is, at high speed, extended into a thread, which is subject to instabilities (according to Rayleigh and Tomatika), and which, therefore, breaks up into a row of droplets (see MT 9.1.5). 

A similar equation results for cBrm. Now a priori we do not know (d In Ja/dcB), cAr, cBr, or K we do not know BAa and Bbb (see Equations 67 and 68) from measurements on pure A and pure B. We have no way of knowing ir a priori, so we cannot use equations similar to 28 or 31. Similar considerations apply if vA vB and = b- Thus, it appears at present that we are forced to use the Archibald experiment or sedimentation equilibrium experiments at different speeds to analyze mixed associations when one is restricted to Rayleigh and/or schlieren optics.
