Pole height

The last two criteria, in particular, are suitable for comparing separating efficiencies in the batch distillation of binary mixtures. The concept of the pole height was then... 

Definition of pole height in batch distillation (after Bowmiin and Cichelli)... 

In the calculation of the plate number for batch distillation Zuiderweg [158] takes into account the influence of the total hold-up and the magnitude of the transition fraction. Mixtures having ix-values from 1.07 to 2.42 were used to study the dependence of separation sharpness on relative total hold-up, reflux ratio and plate number. By means of the pole height S the optimum reflux ratio can be determined. The method corresponds to the determination after McCabe-Thiele with a final state. cs = 5 mol%. 

Figure 7.8 illustrates a distribution system composed of (a) the distribution pole and (b) a customer s house. A distribution pole is made up of a steel pipe, a steel frame with concrete cement, or wood with a down conductor. The ratio of the pole height and the basement length h2 is about 1 3. A customer house involves the groundings of home appliances and a telephone line, that are made up of either copper or a steel rod with a length of about 1 m. 

Daoming wants to know the height of a telephone pole. He measures his shadow, which is 3 feet long, and the pole s shadow, which is 10 feet long. Daoming s height is 6 feet. How tall is... 

Direct photochemical breakdown is the main cause of the decrease of mixing ratios with height for these trace gases at tropical and mid latitudes. In contrast, dynamic transport processes force the distribution and the high variability of tracer mixing ratios in the winter stratosphere at the poles. 

Figure 6 Two-dimensional contour plot of the sum of the harmonic-oscillator and of the electron-repulsion potentials for two electrons in the internal space (xa, ya) for coxy = 5.0 (a), 1.0 (b), and 0.1 (c). The maximum potential height Vmax and the domain of the xa and ya coordinates displayed are the same as used in Figure 3. The red spot at the origin of the contours represents the potential pole of the electron repulsion potential. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this book.)...

Fig. 53 a Topography of two P(VDF-co-TrFE) nanostructures (height 75 nm) fabricated with DPL. b Piezoresponse image of the same structures before a voltage pulse, c PFM image after the application of a voltage pulse (A17=-19 V Ar=20 ms), PFM measured with 700 mV at 35 kHz. The newly formed domain is marked by an arrow. The lower left domain (black dot in b) was poled in a previous scan under the same conditions...
