Inertia peak

It should be noted that the spaeings between the experimentally observed peaks in HCl are not eonstant as would be expeeted based on the above P- and R- braneh formulas. This is beeause the moment of inertia appropriate for the v = 1 vibrational level is different than that of the v = 0 level. These effeets of vibration-rotation eoupling ean be modeled by allowing the v = 0 and v = 1 levels to have rotational energies written as... [Pg.409]

In parallel with the new approaches to generating capacity additions, the utilities, with encouragement from regulators, introduced incentives during the 1980s for reducing load demand. Since the system peak hour load provided the inertia for capacity requirement definition, shaving of the peak became the focus of these incentives. [Pg.1202]

Inertia load (torque). This is usually determined by the manufacturer of the driven equipment and is evaluated by determining the time for the machinery to drift to a stop, being retarded by its own friction. Peak, fluctuating, or shock loads and their cycles or repetition must be considered. [Pg.616]

Since the forward peak is clearly from high J collisions, it is clearly produced via a rapidly rotating intermediate exhibiting an enhanced time delay. Further insight into the associated dynamics is provided by a classical trajectory simulation by Skodje. The forward peak results from the sideway collisions of the H atom on the HD-diatom (see Fig. 37). At the point where the transition state region is first reached, the collision complex is already oriented about 70° relative to the center-of-mass collision axis. The intermediate then rotates rapidly with an angular frequency of u> J/I, where / is the moment of inertia of the intermediate. If the intermediate with a time delay of the order of the lifetime r, the intermediate can rotate... [Pg.147]

Because these loads are usually suddenly applied, and because they last from fractions of a millisecond to at most seconds, the response of or damage to loaded structures or objects is almost always dynamic. So, usually structural response or damage is dependent not only on the amplitude (peak overpressure) of the applied blast loading, the loaded area and the structural strength but also on the mass or inertia of the structure, and either the duration of the transient pressure loading or the applied specific impulse. [Pg.18]

A reactor of volume 3.5 m3 has a design pressure of 14 barg. A worst case relief scenario has been identified in which a gassy decomposition reaction occurs. The mass of reactants in the reactor would be 2500 kg. An open cel test has been performed in a DIERS bench-scale apparatus, in which the volume of the gas space in the apparatus was 3,800 ml, and the mass of the sample was 44.8 g. The peak rate of pressure rise was 2,263 N/m2s at. a temperature of 246°C, and the corresponding rate of temperature rise was 144°C/minute. (These values include corrections for thermal inertia.) The pressure in the containment vessel corresponding to the peak rate was 20.2 bara. [Pg.61]

Besides, the review could conditionally be divided in accord with another criterion, (a) In Sections III-V and VII we discuss so-called unspecific interactions, which take place in a local-order structure of various polar liquids, (b) In Sections VI-IX we also consider specific interactions [16]. These are directly determined by the hydrogen bonds in water, are reflected in the band centered at 200 cm-1, which is termed here the R-band, and is characterized by some spectral features in the submillimeter wavelength range (from 10 to 100 cm-1). Note that sometimes in the literature the R-band is termed the translational band, since the peak frequency of this band does not depend on the moment of inertia I of a water molecule. [Pg.73]

A. Previous models of water (see 1-6 in Section V.A.l) and also the hat-curved model itself cannot describe properly the R-band arising in water and therefore cannot explain a small isotope shift of the center frequency vR. Indeed, in these models the R-band arises due to free rotors. Since the moment of inertia I of D20 molecule is about twice that of H20, the estimated center of the R-band for D20 would be placed at y/2 lower frequency than for H20. This result would contradict the recorded experimental data, since vR(D20) vR(H20) 200 cm-1. The first attempt to overcome this difficulty was made in GT, p. 549, where the cosine-squared (CS) potential model was formally (i.e., irrespective of a physical origin of such potential) applied for description of dielectric response of rotators moving above the CS well (in this work the librators were assumed to move in the rectangular well). The nonuniform CS potential yields a rather narrow absorption band this property agrees with the experimental data [17, 42, 54]. The absorption-peak position Vcs depends on the field parameter p of the model given by... [Pg.203]

More than in GC, the relative areas of the peaks of a chromatogram often do not have anything to do with the molar or mass composition of the mixture analysed. However, the detector, irrespective of its nature, is required to unite a number of fundamental properties. It should give, for each compound of interest, a response that is proportional to the instantaneous mass flow (indicated by its linear dynamic range), be sensitive, have a small inertia, filter most background noise and be stable over time. [Pg.81]

An important feature of the LIB state (it is confirmed by experimental data) presents a strong isotopic shift of the loss-peak frequency vor. Since in the chosen (hat) potential a polar molecule librates almost freely, vor is determined by the moment of inertia 7or(H20), which comprises about half of 7or(D20). Therefore, vor(H20) Z2vor(D20). [Pg.342]
