## Chemical Engineering homework help

For the steady flow of an unspecified fluid through a cylindrical conduit (pipe, cylindrical airduct, blood vessel, etc.) the velocity profile has been determined from a differential equation relationship based upon the fluid contact force per unit area as:

Fluid Velocity Distance from Pipe Wall

y’ y’ < 5

u’ = – 3.051 + 5 ln y’ 5 < y’ < 30

5.49 + 2.52 ln y’ y’ > 30

where u’ is the dimensionless velocity in the x-direction and y’ is the dimensionless y-direction coordinate and:

u’ = u √o /

and,

y’ = y √o / / v

where u is the fluid velocity (m/s) in the x-direction, o is the fluid shear stress (Pa), is the fluid density (kg/m3), y is the distance (m) from the pipe wall, and v is the kinematic viscosity (m2/sec). If the x-direction velocity depends only upon the vertical distance (y) from the pipe wall, please determine the following.

a.) Using only the flow system description provided (without the velocity distribution information) with the definitions of the fluid velocity vector (V) and the acceleration field vector (a), determine general expressions for the differential continuity equation acceleration and vector fields for this flow system (50 POINTS).

b.) If the fluid is air at the conditions of 70.1 oF and 2.25 atm and flows through a 2.35 foot inner diameter pipe, determine the Reynolds number and the flow regime. Also determine the general continuity expression for this flow system and its boundary conditions. Assume that absolute fluid viscosity is a weak function of pressure (35 POINTS).

c.) Determine the shear stress distribution of the fluid in this system using the information from Parts (a) and (b). Please state all assumptions. (15 POINTS)

d.) Formulate the simplified Navier-Stokes Equations for the system described. Please state all assumptions (15 Points – BONUS)

Paper

Your research paper assignment will consist of five parts – the summary of the article, the analysis of presentation and organization, a properly structured Citation (APA) for your article (librarians can help you with this as well), a copy of the article (uploaded PDF), and the completed librarian prescription. Your paper should not have a separate title page. On the top right-hand corner of the first page type your first/last name and nickname if you have one as well as Chem 171 – Fall 2020. Approximately one-third down the page and centered, include journal name, title of the article, and the first author listed. Use a standard 12-point font such as Times New Roman and be double spaced.

Summary

(1-2 pages): The summary must show that you have read the article completely and carefully. Even if you do not understand most of the article, describe to what level you do understand it. It may help to imagine telling a fellow student about the article. It is best to write everything in your own words, but it is acceptable to include up to two short quotations. Use third person throughout your analysis.

Analysis of Presentation (approx. 1 page):

The analysis of presentation and organization should essentially answer the following questions: Was the article segmented into sections? If so, what were the sections? How helpful was the abstract in summarizing the article? How is the style of writing different in a science journal compared to other forms of writing? What are the similarities and differences between our laboratory reports and the presentation style in the journal article? How descriptive were the titles for figures, graphs, and/or tables?

Citation: Show how you would reference your article using APA format.

## Chemical Engineering homework help

1-Briefly introduce the topic of the paper. What is it, and why is it important?

2) Thermodynamic background / theory. explain the equations that are applied

3) What is measured. Describe the actual measurement, or what should be measured (if you are describing a method).

4) Comparison to data. Either show how the thermodynamic principles introduced above have been compared to data, or discuss how they could be. Make sure it is clear what thermodynamic information is determined.

5) Reflection. Discuss the limitations in the cases the model can capture, the reasons for any deviations or limitations. Are there ways that the model could be improved?

6) References. Provide references cited. The primary source should be peer‐reviewed, and other journal articles or books can be used for support. Provide the authors, article title, journal, volume, pages (or article number), and year, in a consistent citation format. Non‐peer reviewed sources that have no author attribution (such as Wikipedia) are much less valuable sources of information.
