Recommended for students considering graduate study. A ten kilometer circle should be drawn around both the start and end points of the attack. This could cause some serious OPSEC problems, especially for frontline troops. The Gradient of a Vector Field In addition to the scalar product (V. v) and the vector product [V X v] one may also form the dyadic product Vv: This is called the gradient of the vector v and is sometimes written grad v.

The Reynolds number at the upper end of the transition range is 5 X 106. There is no pressure gradient or gravity force in the x direction, and the flow is presumed to be laminar. The solid arrows repre- sent the first unit vector in the dyadic product, and the hollow vectors the second. Chilling and Freezing of Food and Biological Materials. For instance, a tank Weber number or a drop Weber number may be useful. In a typical low-temperature process, the feed to the isomerization plant is n-butane or mixed butanes mixed with hydrogen (to inhibit olefin formation) and passed to the reactor at 230°-340° F and 200-300 psi.

In Case (ii) the velocity components become infinite at the corner as a - 1 is then negative. (c) The complex potential can be decomposed into its real and imaginary parts w = 4 + it,b = -cua(cos a6 + i sin a61 (4.3-44) Hence the stream function is 1C, = -cyn sin a0 (4.3-45) To get the streamlines, one selects various values for the stream function-say, $,, $,, t,b,. , -and then for each value one plots r as a function of 0. (d) Since for ideal flow any streamline may be replaced by a wall, and vice versa, the results found here for a > 0 describe the inviscid flow over a wedge (see Fig. 4.3-4).

Interfacially embedded coordinates are used in this discussion, with a piecewise smooth interfacial grid as in Fig. 20.4-1. J.: Conduction Heat Transfer, Addison-Wesley, Cambridge, MA, 1955. Examples of dispersion processes are suspending of solids, dispersing of gases in liquids, and mixing of immiscible liquids such as are encountered in emulsions and in liquid-liquid extraction.

These situations were essentially cases of conduction or conduction together with heat generation. In fact, Brownian motion is often significant up to a particle size of 3 pm, depending on the relative density difference. The theories of mass, momentum and energy transfer were being taught at that time only to the extent necessary for a narrow range of applications. Interfacial tension, contact angle, wetting, transport phenomena near interfaces, properties and stability of colloids, colloid transport phenomena, surfactant, micelles and emulsions. 3 hr. lec. 3 hr.
