  Problem 8: 49

  Water is the working fluid in an ideal regenerative Rankine cycle with one closed feedwater heater. Superheated vapor enters the turbine at 10 MPa, 480 C and the condenser pressure is 6 kPa. Steam expands through the first stage turbine where some is extracted and diverted to a closed feedwater heater at 0.7 MPa. Condensate drains from the feedwater heater as saturated liquid at 0.7 MPa and is trapped into the condenser. The feedwater leaves the heater at 10 MPa and a temperature equal to the saturation temperature at 0.7 MPa. Determine for the cycle.

  1. a) the rate of heat transfer to the working fluid passing through the steam generator in kJ per kg of steam entering the first stage turbine.
  2. b) the thermal efficiency
  3. c) the rate of heat transfer from the working fluid passing through the condenser to the cooling water in kJ per kg of steam entering the first stage turbine.

  Problem 8: 60

  Consider a regenerative vapor power cycle with two feedwater heaters, a closed one and an open one as shown in the figure. Steam enters the first turbine stage at 12 MPa, 480 C and expands to 2 MPa. Some steam is extracted at 2 MPa and fed to the closed feedwater heater. The remainder expands through the second stage turbine to 0.3 MPa where an additional amount is extracted and fed into the open feedwater heater operating at 0.3 MPa. The steam expanding through the third stage turbine exits at the condenser pressure of 6 kPa.

  Feedwater leaves the closed heater at 210 C, 12 MPa, and condensate exiting as saturated liquid at 2 MPa is trapped into the open feedwater heater. Saturated liquid at 0.3 MPa leaves the open feedwater heater. Assume all pumps and turbine stages operate isentropically. Determine for the cycle

  1. a) the rate of heat transfer to the working fluid passing through the steam generator, in kJ per kg of steam entering the first stage turbine.
  2. b) the thermal efficiency.
  3. c) the rate of heat transfer from the working fluid passing through the condenser to the cooling water in kJ per kg of steam entering the first stage turbine.

  trustee) will make 40 more $2,500 payments until a 46th and final payment is made on Steve’s 65th birthday. The grandfather set things up this way because he wants Steve to work, not be a “trust fund baby,” but he also wants to ensure that Steve is provided for in his old age.
  Until now, the grandfather has been disappointed with Ed, hence has not given him anything. However, they recently reconciled, and the grandfather decided to make an equivalent provision for Ed. He will make the first payment to a trust for Ed today, and he has instructed his trustee to make 40 additional equal annual payments until Ed turns 65, when the 41st and final payment will be made. If both trusts earn an annual return of 8%, how much must the grandfather put into Ed’s trust today and each subsequent year to enable him to have the same retirement nest egg as Steve after the last payment is made on their 65th birthday?

  Frankenstein Critical Analysis Evaluation Essay

  Note: Please review the source guidelines below very carefully. If you do not choose from the

  provided sources below, this will cause a grading delay and you will need to resubmit the

  assignment.

  For this assignment you will write your evaluation essay. You are required to submit only your final draft for this assignment (though we encourage all students to take advantage of the additional feedback a draft can provide). Use the grader’s feedback and the rubric to make revisions to your draft before submitting the final. Your second draft will be graded.

  Now that you have completed Mary Shelley’s Frankenstein, you are in a good position to consider what critics have written about the novel. You will need a total of two critiques (also known as critical analysis essays) for this assignment.

  First, use the selection of links below to locate a critical analysis essay written about the 1818 version of Mary Shelley’s novel. You may focus most of your attention on this first critique.

  Choose from among these sources:

  ü ipl2 Literary Criticism collection: If you use this site, you must choose from the first seven critiques listed as the final two are not scholarly:

  ( http://www.ipl.org/div/litcrit/bin/litcrit.out.pl?ti=fra-63

  ü Professor Sherry Ginn’s critique:1 http://www.clas.ufl.edu/ipsa/2003/ginn.html

  ü Professor Naomi Hetherington’s

  critique: http://knarf.english.upenn.edu/Articles/hether.html

  The questions in the study guides should have helped you evaluate this criticism in your head. Now it’s time to write it down! Your evaluation may go more smoothly if you approach the guiding questions in this order:

  1. Evaluate the critic/author:

  Who wrote the criticism you read? What credentials does the author have (education, professional career, other publications, etc.)? (If you are using a credible author, you should be able to find her/his credentials fairly easily)

  2. Find the thesis of the article:

  What is the thesis of the critical article you’ve chosen? What point does the author want to make about Frankenstein?

  3. Evaluate the thesis:

  1 Note: You should avoid reading Ginn’s article too simplistically. A common misperception is that Ginn is arguing in favor of this novel being an autobiography, but if you read her article in full, you will find that this isn’t really the case. If you misinterpret your chosen source, it will affect your own arguments, so please read carefully.

  Do you agree with this thesis? Why or why not? We’ve covered many ideas in the study guides. Can you find points within the guides that support your agreement or disagreement with the critical writer(s)? Look for new supporting information rather than revisiting the same ones the critics have chosen.

  4. Evaluate the support:

  Whether you agree or disagree with the thesis, does the critic provide sufficient research from the text and outside references to make a strong case? What does the article have for support from the text or outside sources? In your opinion, what makes these references valid? Do you feel the author uses this support properly?

  Next, locate a second critique about the novel, and discuss how this second critique agrees and/or disagrees with the first one. For instance, if the first critic argues that Shelley’s writing is juvenile, does the second critic agree with this assessment? If the first critic believes the novel is autobiographical, does the second critic concur? These are just a few examples of how you can include this second critique in order to have a polished, comprehensive Evaluation Essay of your own.

  In addition to addressing each of the evaluative components above, develop your essay so it has a clear introduction, body, and conclusion. You must include an evaluative thesis statement both the introduction and the conclusion. Ensure that each of your claims are supported with valid evidence from the literary criticism you have chosen, the novel, Frankenstein, and/or the study guides.

  Using proper MLA2 style, insert parenthetical citations for all borrowed information in addition to a Works Cited page for Frankenstein and your chosen literary critiques; you are not required to cite the study guides if you use them.

  Hint: For a thesis statement, try answering a question like: How and how well does this piece of criticism state and support its argument regarding Frankenstein?

  You might use these as possible guidelines in crafting your thesis statement:

  (Critic, aka author of the critique) uses (add critic title) to (add an adjective to describe the effectiveness of the argument such as “adequately” or “inadequately”) argue that (add critic’s thesis) by (explain why and/or include your support).

  OR

  (Critic)’s (add critique title) (add an adjective to describe the effectiveness of the argument such as “adequately” or “inadequately”) argue that (add critic’s thesis) because (explain why and/or include your support).

  More specific thesis examples:

  2 Tip: Review the course topics for MLA resources. Failure to use MLA style will mean a point deduction.

  John Smith uses “Frankenstein Critique Essay” to adequately argue that Victor’s mother created the first monster by coddling Victor as a boy.

  OR

  John Smith’s “Frankenstein Critique Essay” does not effectively argue that Victor’s mother created the first monster because the novel Frankenstein too strongly supports inherent good or bad, which means nurturing roles cannot be held responsible.

  The guidelines for this assignment are as follows:

  Length: This assignment should be at least 750 words.

  Header: Include a header in the upper left-hand corner of your writing assignment with the following information:

  • Your first and last name
  • Course Title (Composition II)
  • Assignment name (Evaluation Essay)
  • Current Date

  Format:

  • MLA-style source documentation and Works Cited3
  • Your last name and page number in the upper-right corner of each page
  • Double-spacing throughout
  • Standard font (TimesNewRoman, Calibri)
  • Title, centered after heading
  • 1” margins on all sides
  • Save the file using one of the following extensions: .docx, .doc, .rtf, or .txt

  Underline your thesis statement in the introductory paragraph.

  Reminder: You need at least two critiques in addition to the novel in Works Cited in order to receive the highest score. In other words, you need three sources total in cited in the essay and on the Works Cited page in order to earn the maximum points in the corresponding column on the grading rubric. Failure to meet the source minimum will result in a severe decrease in your grade.
