A Generalized Thermodynamic Correlation Based on Three-Parameter Corresponding s There is a correlation between thermodynamic and volumetric functions. The article by Byung IK Lee and Michael G. Kesler elaborates a generalized correlation basing on the three corresponding states. The three states were proposed by Pitzer and his co-workers. The three states are fundamental and widely used in process design. The original work by Pitzer basing on the same principle was designed within a temperature limit of 0.8. Since then, there have been the development of various correlation in the last five years which have been presented in tabular form but, unfortunately, they cannot be implemented in computers (Lee and Kesler). Moreover, there are discrepancies existing between the extended and the original correlations’ interface.
The main objectives of the paper are the development of the analytical correlations basing on the stated three – parameter corresponding state principle. Also, the work is aimed at covering the whole range of Tr and Pr in the practical application of hydrocarbons processing (Lee and Kesler). Furthermore, the work focuses on the improvement of consistence and accuracy of the pre-existing correlations. The achievement of the above stated objectives was based on the two state equations that are similar to Rubin, Benedict and general fluid reference (Lee and Kesler).
In the paper, there is the description of the methodologies that can be efficiently used in the in the representation of the thermodynamic functions and volumetric functions. The description is based on the on the 3-parameter corresponding state principle proposed by Pitzer (Lee and Kesler). The functions referred in the description include fugacity coefficients, densities, enthalpy departures, isochoric and isobaric. The description of the methodologies has resulted in the generation of two equations of state that can be effectively used for reference fluids and the two equations are adequately used to represent both the thermodynamic and volumetric properties of both vapour and fluids as a function of the pre-stated 3-parameters within a range where Tr =0.3 to Tr =0.4 and Pr = 0 to Pr = 10. Using the above stated analytical form, there is an improvement in the representation of the properties at critical regions and within low temperatures (Lee and Kesler).
The article concludes that, the stated methods are reliable and due to this; they have found wide applications in various in various conditions. Also, it is connoted that the accuracy of the methodologies can be compared to the original Pitzer correlations, and the accuracy is best in sub cooled and superheated regions. Despite this, there is a small discrepancy in the accuracy when compared to Pitzer correlations in some conditions. This diminishing accuracy occurs at saturated conditions and retrograde and critical regions during its application in widely boiling mixtures (Lee and Kesler).

Generalized Anxiety Disorder

...? General Anxiety Disorder General anxiety disorder is a type of anxiety disorder which includes prolonged tension and worry about everyday things. Everyone gets worried but if the person continues to worry unnecessarily about everyday things to the extent that his performance gets affected and he is unable to properly function and relax then he is surely a patient of general anxiety disorder. This anxiety is less intense as compared to other types of anxiety disorders but is long lasting and makes relaxation almost impossible for the patient. The patient of General Anxiety disorder generally worries about the things that a normal person would worry about like money, health issues, family issues, work problems, etc. but they worry... to an...

Optical parameter

...? Optical Parameter Optical parameter involves reflection, refraction, and absorption. In all these cases, light is propagated as rays. A ray, in this case, is defined as an instrument used to model the propagation of light. The rays of light are normally propagated in a path that is considered rectilinear whenever they travel in any medium (Erik, 2004). At the interface of two media that are not similar, a ray would bend, curve if in media that changes its refractive index, reflected or absorbed. Optical parameters determined the propagation of the rays in an optical system depending on the wavelength of the ray. This vital optics simplification does not account for the effects of optics...

Correlation

...of the internet. A negative correlation means that teachers are comfortable with the new facilities but still they are not making effective use of it. If it is negative the real objective cannot be said to be achieved. A minimal relation means that the teachers are not comfortable with the new facilities so they are not making effective use of it. This is also unfavorable for the contributor. References Goolsbee, Austan D & Guryan, Jonathan. (2003). Closing the Digital Divide: Internet Subsidies in Public Schools. Capital Ideas.

...Themes and Corresponding Works In APA Format Robert Frost needs absolutely no introduction; he was one of the finest poets of his time. He wrote several inspiring poems, The Road not Taken is arguably his best poem of all time. On the surface level it seems like any other poem but it has deep meaning hidden in it and one can only decipher the hidden meaning should it be read several times. Like Robert Frost, Emily Dickinson also needs no introduction. Because I could not stop for death is another very fine poem which teaches the readers more important things than one. This paper will juxtapose the two poems and all the important literary elements will be expansively presented in this paper. The use of language in The...

Generalized Anxiety Disorder

...sometimes makes individuals with GAD to abstain from everyday tasks (NIMH, 2014). Gad has been shown to be associated with certain families, but it is not clear why some individuals would be affected and not others. Moreover, researchers have indicated that several parts of the brains are involved in generation of fear and anxiety (NIMH, 2014). The understanding of the role of the brain in development of the condition may play a significant role in coming up with effective forms of treatments. The condition has attracted significant attention in the United States. This is because of its effect in the general population. The condition has been shown to affect about 3.1% American adults...

Correlation

...Correlation Correlation is very and is the statistical measure that gauges the relation of two sets of numbers that lie between-1 to 1. Correlation is very important when it comes to mathematics. It helps so much in the investing world since it helps the investors to minimize the risk since by the use of portfolios with those assets that have low correlation with one another. Correlation is also important since in this case causation does not apply. The other importance of correlation is that hypothesis in this case is stated in correlation. Causation requires correlation for it to be...

...color (Long, 2003). In conclusion, the play and the poem both depict racialism. Racialism and negative ethnicity is an aspect that affects the current society. In as much as many states have initiated laws aimed at protecting the public against racialism, this vice is still practiced. Racialism is a very negative social aspect, and this is because it always leads to the humiliation of a group that is racially abused. This is in the case of Thebedi, whose child was killed by her former lover, just because the child was born from a black woman. On the other hand, for purposes of seeking to escape from her race, the young black girl aspires to be like a white woman. This means that she does not see any value of being a...

Thermodynamic and Fluids Report

.... The results will allow for the modeling of the observed patterns. The flow of fluids in open flow systems are based on Bernoulli’s principle. This principle is basically based on mathematical techniques and can therefore be used to model the flow of the fluids. The Flow of fluids is vector in nature and therefore using Euler’s equations in the vector form, we can determine the rectangular, streamline and cylindrical coordinates of the open flow of the fluid under study. By integrating Euler’s equations along the streamline steady flow, we can be in a position to model the Bernoulli’s equation for the flow of the fluid. The flow of fluids in devices considered to be open flow is normally affected by...
