Vector triangle

Figure 5-20. impeller inlet and outlet flow vector triangles. 

Figure 5-21 includes an outlet velocity vector triangle for the various vane shapes. Figure 5-20 shows a backward curved impeller that includes the inlet and outlet velocity vector triangle. Because most of the compressors used in process applications are either backward curved or radial, only these two types will be covered in detail.

At 795 cm 1 LiI03 has a transverse A phonon. Fig. 5 shows the shift of the Raman line towards lower wave numbers for decreasing angles between the directions of the incident and scattered light. Because the wave vector triangle lies in the isotropic Ary-plane, k is always perpendicular to the optical axis and no directional dispersion is to be expected, therefore the shift of the line is due only to the variation of the magnitude of the wave vector. 

Turning now to the configuration of the top surface of the capillary we have the fact, as previously discussed, that this surface will be determined by the vector triangle of the tensions involved at. the common line of contact. The pressure at any point on this surface will be given by Eq (15-1). 

Vectors can also be added using a vector triangle, as explained in the following example. 

Solution. Let the velocity of the stream be S and the velocity of Pat be P. These two vectors are added using a vector triangle in the following way. Draw the vector P (see figure d). Draw the vector S starting at the point where P ends. Then complete the triangle of vectors with the resultant vector R as the hypotenuse. Draw an arrow on the vector R in the direction from where P starts to where S ends, as shown in the figure. Write... 

FIGURE 8.6 For any native phase angle p the vector triangle T ru = F/> + fn fails to close by an amount e(p). which is termed the lack of closure error. The phase angle of maximum probability, that for which e(p). is minimized when considered over all isomorphous heavy atom derivatives. 

The idea of a vector triangle provided the eventual solution to the phase problem. Three associated vectors with appropriately linked properties should be able to form a triangle in vector space (Figure 6.6). Given the fact that each F(hkl) structure factor, corresponding to a given set of h/cHattice planes, is also a vector in the complex plane, then the idea was...
