FIG. 6-57 Drag coefficients for spheres, disks, and cylinders A = area of particle projected on a plane normal to direction of motion C = overall drag coefficient, dimensionless Dp - diameter of particle Fd = drag or resistance to motion of body in fluid Re = Reynolds number, dimensionless u = relative velocity between particle and main body of fluid (I = fluid viscosity and p = fluid density. (From Lapple and Shepherd, Ind. Eng. Chem., 32, 60S [1940].)... [Pg.52]

The usual description of this situation is in terms of the dihedral angle between the H-C-C-H bonds. The dihedral angle is obvious in the Newman projection as it is the angle between the two C-H bonds projected on a plane orthogonal to the C-C bond. In a Newman projection this plane is the plane of the paper, and here the angle is 180°. [Pg.824]

Angle between the 2p7i orbital and the C-H i bond projected on a plane perpendicular to the C-C bond direction. [Pg.13]

These angles are shown stereographically in Fig. 9-10, projected, on a plane normal to the incident beam. The (111) pole figure in (a) consists simply of two arcs which are the paths traced out by 111 poles during rotation of a single crystal about [100]. In (b), this pole figure has been superposed on a projection of the reflection circle in order to find the locations of the reflecting plane normals. Radii drawn... [Pg.301]

Brownian motion. Projection on a plane of the trajectory of a gamboge particle, taking observations at constant time intervals. The right-hand side shows the same trajectory, but the time interval is 10 times shorter than at the left-hand side. After observations by Perrin. See text. [Pg.132]

It will be clear from the above discussion that if the ternary eutectic curves are projected on a plane parallel with the face BC of the prism, that is, if we express the composition of the solutions in accordance with the formula xA, yB, (100 ) C, then it will be possible to state, from the form of the curve obtained, whether or not the two components present in varying amount crystallise out pure or combine with each other to form a compound. It will be apparent that the projections of the ternary eutectic curves in the manner indicated, will yield a series of curves similar to the binary curves given in Figs. 33, 37, and 43, pp, 103, 109 and 119.

unit cell of the hexagonal structure of nickel arsenide, NiAs, projected on a plane perpendicular to the z axis, (b) Clinographic projection of the same structure. The two As atoms represented by heavy circles are those within the unit cell the others lie outside the cell but have been added to show the co-ordination about the Ni atom at o, o,... [Pg.142]
