Drawings and performance curve

Data Table 2 shows values of 0 that are obtained for initial y-position values of 1.5 X 1(T13 m to 7.0 X 10 13 m. (You may like to perform these calculations on a spreadsheet.) Graph the initial y-position versus 0 and draw a smooth curve through the data points. Label this graph Figure C. 

Measured the relationship between the gas desorption index of drill cuttings K, and gas pressure of the coal samples in the laboratory, and draw the relation-curves of K, and gas content W combined with the proximate analysis of the samples. The relation between K, and W is in accords with exponential function by performing analysis of the measured data. According to the physical chemistry theory, the non-linear characteristic between the two is caused by the diffusion coefficient changing constantly with the gas content in... 

During this period, additional data is collected, including data associated with motor amperage draw, pump curve performance, interface control, and operational baseline parameters, such as noise, vibration, and performance specifications are initiated. 

Since the 1980s, with wide applications of the highly automated X-ray spectrometer, scientists have used X-ray spectrometry to perform quantitative analysis of phase. This analysis principle is based on the relationship between phase content and diffraction intensity, and the method is simple and fast. Its accuracy can also meet the requirements if its component is not too complex. There are more than 20 quantitative methods such as internal standards, external standards, nil standards, adiabatic methods and theoretical calculations etc. Generally speaking, the more mature internal standard method requires a lot of time to draw the standard curve, and the curve can only apply to one matter, so this method has certain restrictions in quantitative analysis. In 1974, F. H. Chung proposed a skeleton washing method , also called as if-value method, which greatly simplified the X-ray quantitative analysis method, and has been widely used in various research fields. 

Since this draw tray is a chimney tray and performs no fractionation, the temperature of the condensed liquid leaving the tray is estimated as being the dew point of the hydrocarbon vapor from the flash zone at the hydrocarbon partial pressure above the draw tray, the leakage air and the bottoms ste being defined as inerts. The temperature at this pressure is read from the vacuum region EFV curves. The vapor temperature leaving the grid is estimated in the same way but referred to the total pressure at that point. 

As we mentioned before, the number of cut-point ranges is arbiharily defined. Kaes [32] states that it is necessary to perform a sensitivity test to study the relationship of the side draw rate to the side draw temperature and the associated distillation curve to ensure that the defined BP-based pseudocomponents are able to provide reasonable results. If the relationship is stepwise rather than continuous, the number of BP-based pseudocomponents needs to be redefined. In this work, we cut the reactor model effluent into 20 TBP pseudocomponents to represent the feed to fractionators. To run the sensitivity test, we change draw rates of diesel fuel to investigate the relationship among draw rates, draw temperatures, and distillation curves of products. 

The ratio of stress to strain in the initial linear portion of the stress—strain curve indicates the abiUty of a material to resist deformation and return to its original form. This modulus of elasticity, or Young s modulus, is related to many of the mechanical performance characteristics of textile products. The modulus of elasticity can be affected by drawing, ie, elongating the fiber environment, ie, wet or dry, temperature or other procedures. Values for commercial acetate and triacetate fibers are generally in the 2.2—4.0 N/tex (25—45 gf/den) range. 

The curves shown in Fig. 5.78 indicate the ability of the model to give a reasonable description of the performance of the fermentations. The authors of the paper, however, draw attention to the fact that that the prediction of the RNA component was nowhere as accurate and concluded that the model had failed. This, they pointed out, was a necessary test to prevent the model from becoming merely a curve fitting exercise as opposed to a mechanistic model. 

The linear range of a detector is defined as the range of concentration over which the sensitivity is constant to within a defined tolerance. S is obtained by performing a linear regression analysis of the data. A simple way to determine the linear portion is to draw a second line having a slope equal to 95% of that of the best-fit line. It intersects the response curve and determines the Unear range (Fig. 17). 

One possibility to analyze the tableting process is to describe the areas under the curve during compression and decompression and to draw conclusions on plastic and elastic parts of deformation. Emschermann and Muller [91] applied this method to data from eccentric machines (Figure 14). Similar area comparisons were performed by the research group of Schmidt [92-94] for rotary machines (Figure 15). They tried to gain information on elasticity by calculating differences between the area under the plot in the compression phase and the area under the plot in the decompression phase. A sophisticated technique to interpret area data under one...
