Velocity triangles relative

The regulation of axial fan blade angle also influences the inlet and exit velocity triangles in such a way that the axial velocity and thus the volume flow change. When the relative velocity remains parallel to the blade, the efficiency remains high (Fig. 9.52). [Pg.771]

Fig. 8. Relative velocity dependence of integral cross sections calculated for Na + O collisions for the indicated exit channels. The solid curve is the charge transfer cross section calculated using a multichannel Landau-Zener formalism (see text). The dashed curve is the two-state Landau-Zener cross section. Charge transfer calculations by van den Bos are indicated by triangles. Full circles and squares are the respective excitation channels as determined using the multichannel Landau-Zener model.

Fig. 10 Plots of (7) and (8) for RT within v = 0 from N2(0 10) and VRT N2 (1 10) —> (0 Aj). Filled squares represent the A-plot (7), circles the E-plot (8) for RT and triangles that for VRT. The vertical arrow indicates the mean relative speed at 300 K. From this it is evident that only velocities in the high-energy region of the MB distribution may open the VRT channels are hence the process is of low inherent probability. The shaded region indicates those channels and velocities for which energy and AM conservation are simultaneously conserved...

Further, applying Pythagoras s theorem to triangle BCE in Figure 15.3 produces an expression for the magnitude of the inlet velocity relative to the blades, Cri. [Pg.178]

FIGURE 2. Fraction I/Iq of the transmitted beam of O atoms as a function of the reduced parameter B/v, where B is the magnetic induction across the beam and v is the velocity of the atoms. (Black triangles, open dots, black dots, open triangles correspond to 1.33, 1.60, 1.80 and 2.21 km s" ). The Ml line is calculated for the ground 3pj state, the dashed line for the metastable E>2 state. In the lower panel, the relative weights Wj of the ij mj> states of 0(3pj) are shown. [Pg.181]

Figure 6.9 Velocity vector diagram (Newton diagram, Section 2.2.7.2) showing the relation between the lab velocity of the product Kl, vj, and its recoil velocity with respect to the center of mass, u, . The initial relative velocity v = v< - V j = u< - Ui forms the hypotenuse of the Newton triangle. The center of mass is as indicated, uj, is the recoil velocity of the Kl scattered (shown here in the plane defined by the initial velocities) at a center-of-mass (c.m.) angle 0 with a given Bj. The cone of isointensity (given 9 and variable ), see Figures 4.6 and 6.10, is indicated by the dotted circle. All lab velocities v are solid lines, center-of-mass velocities u are dashed.
