This is also known as air dilution, and is a common procedure for gas-fired boilers. It is allowed for any very low-sulfur fuels (less than 0.04 per cent sulfur) or for fuels in the range 0.04-0.2 per cent S where the VLS fuels chimney heights calculation gives a lower value of U than the other fuels calculations. In these cases, the flue may terminate at the uncorrected height U so long as ... 

The amount of tebuconazole residue is calculated by using a least-squares fitting algorithm to generate the best line which can be used to calculate the corresponding concentration for a given peak area or peak height. Calculate the slope and the intercept of the standard calibration curve. 

This limit determined for the barrier to H motion is consistent with the value measured in the IR experiments by Stavola et al. (1988b, 1989b) and also with the barrier height calculated by Denteneer / /. (1988,1989a,b,c). 

Note As measures the difference between the softness of electrophilic attack of the carbon atom of HNC and softness for nucleophilic attack for the X or Y atom of dipolarophile. Values are given in a.u. a Preferred site of attack as determined by barrier height calculations is shown by asterisk ( ). b Correspond to s value. 

Some results are shown in Table 3 together with experimental values where available and also some barrier heights calculated by Pople et al using an ab initio SCF method. 

Substances A and B were found to have retention times of 17-30 and 19-92 minutes respectively on a 25-0 cm column. The widths (at the base) for A and B were 1-10 and 1-22 minutes respectively. The average number of plates in the column and the plate height calculated resolutions.

We have extended the treatment of Franklin and Klug (6) to the case in which presence of an incommensurable helix cannot give rise to splitting of layer lines due to the fact that only one order of Bessel function is significant in controlling the amplitude of the structure factor. In this case, the layer line will be displaced slightly from the height calculated for the commensurable helix. Our example is the crystal structure of the... 

The values of the peak height calculated with Eq. (6.182) have been included in Fig. 6.29b (black dots).

Data can also be collected for manual measurement on simple recorders or on integrators whose capabilities range from those providing a printout of peak areas to those providing chromatograms with peak areas and peak heights calculated and data stored for possible reprocessing. 

Continue the illustration from step 2. Assume that the required cleanup is in fact 90 percent, that 1-5-in ceramic packing is to be used, and that a safety factor of 1.4 is to be used in the height calculation. Then the estimated height equals (safety factor)(Nog)(Hog), i-e-> (1.4)(4.61)(2.5), or 16 ft (4.9 m). 

Crimping Height. Calculate the theoretical crimping height to determine the position of the depth stop in the crimp collet. Knowledge of the theoretical... 

By plotting the theoretical plate height calculated via Equations (8) and (10) over the flow rate, u, the dependence shown in Fig. 2-7 is obtained for an anion exchange column (IonPac AS4). 

Flooding is much more sensitive to vapor rate than to liquid rate. Trays can, however, definitely be flooded by high liquid rates. Prediction of maximum liquid capacity is based on hydraulic calculation of liquid backup in the downcomers. For low-foaming systems, it is often assumed that liquid backup cannot be more than half of the downcomer height, calculated as clear liquid. For high vapor density, e.g., S.Olb/ft the limiting backup is even less. 

From Weiss and Leroi11 average of the harrier heights calculated from each frequency assuming a sinusoidal potential and no top-top interaction. 

By integrated area measurements all other measurements from relative peak heights. Calculated HTC saturated end group concentration prior to irradiation is 556 per 10,000 carbon atoms. 

Temperature dependent I-V measurements in the temperature range 300-500 K, which allowed determination of the activation energy, were also performed, and the results are listed in Table 6.2. The barrier heights calculated from the Richardson plot using Equation (6.2) are consistent with the room temperature values for each sample. However, the calculated effective Richardson constant is much smaller than the theoretically expected value which is commonly reported in the literature for GaN [2]. As we can see in Table 6.2, the effective Richardson constant is also related to the crystal quality, and obviously further work is required to shed light on the discrepancy between the measured and theoretical values endemic to GaN.
