Grading Scale Since class average usually is above 70, there may not be any curving in this course. If not curved, your grade will be assigned to your overall course average as given below: 90-100: A 80-89.9: B 70-79.9: C 60-69.9: D Below 60: F I. Exams Exams shall be open notebook and textbook. Small size blue books shall be supplied for the exams. You may be seated in the exams. Seating charts shall be available on the door of the class room before the exam if I decide to seat you. J. Make-up Exams No make-up exam shall be given unless it is absolutely necessary. You must contact me and get approval to take the make-up exam before the regular exam starts. Only one make-up exam shall be given for all missed exams on the last day of the class. Test shall cover all topics included in all previous exams and may be more difficult than regular exams. K. Home Work Homework is for you to do it at home. You must not solve homework problems together with anyone else since end result may be considered to be cheating. Due hour for the homework sets is on the due date, before class starts. Ten points out of one hundred points shall be deducted for each day of late submission. Holidays and weekends shall not be counted for lateness. No homework sets shall be accepted and graded after they are returned back to class or after five working days of the due date, whichever comes first. Homework due on the weeks of exams must be turned in on time. Last homework set must be turned in, on or earlier than the final exam day and time. Exam re-do homework sets and some other homework sets may be graded based on correct answers only: You may receive no credit if answer is wrong, full credit if answer is correct. A cover page should be attached to each homework set and laboratory report. A copy of cover page is given at the end of syllabus. If you enter any information wrong or leave out some information on the cover page, penalty will be 5 points. If I am left behind in teaching and I did not change the due date of some problems on the set, you are required to submit your homework on time. Please read the material that I did not cover and submit your homework on time. Up to 20% may be deducted if units are not used or incorrectly used. Up to two points out of ten may be deducted if homework sets are not neatly and clearly presented. Submit your homework sets directly to me, just before the class or toss it under my door any time. Homework sets shall be returned to you in about one week's time. If you are late to a class and there is homework due, your homework is also late. 4 L. Attendance Attendance is very important in my courses since I tend to ask questions in exams on the topics I stress on. I shall take attendance from time to time (about once a week). Let me know if you have any serious reasons not to attend a class. Percentage of classes you miss will be calculated using "number of classes missed divided by the number of attendances taken". Two late-comings to a class will count as one class-day missed. You are late if you come-in to the classroom after class start time and you see me inside. M. Policy on W-Grades Due to very strong correlation between the Midterm grade and the course grade, I am recommending you to drop the course if you end up receiving an "F" as your Midterm grade and you do not have very good reason(s) for failing through the end of the midterm exam. "W" grade can only be received if you drop the course before the end of Withdrawal deadline. No grade will appear on your record if you drop the course before the end of Drop deadline. N. Policy on Incomplete Grades No incomplete grade will be passed unless there is an emergency on your part which will not let you complete the course. In order to receive an incomplete grade you must be passing the course at the time of the emergency and must have completed major portion of the course. O. Disability Statement Students capable of success, regardless of their disabilities are admitted to the university. The faculty and staff of the University of Maryland Eastern Shore work cooperatively to assist their students in achieving their educational goals. Moreover, students with disabilities are accommodated in accordance with both federal and state laws. To receive special accommodations for a disability, the student must register with Student Disability Services before any accommodations can be granted. At the time of registering for disability services, please bring documentation to support your claimed disability. The documentation must be within three years and provided by a licensed professional with expertise in the special disability area. If you have questions about disability services or accommodations, please contact Dr. Dorling Joseph at (410) 621-3446. The Student Disability Services office is located in the Student Services Center (SSC), Suite 2169. P. Cheating Any cheating shall be penalized severely. Severeness of penalty shall depend on how much evidence is collected for cheating. I want to make it sure that only those who take the time and do their work will receive the grade. Any student who CHEATs will receive, as a minimum, zero in the exam or in the homework. Depending on the severity of cheating, student may be reported to campus academic authorities for proper penalty. If cheating in any homework set or in any laboratory report is repeated, your homework privileges may be suspended. In this situation weight of the homework sets shall be moved to the exams. Laboratory reports and any home assignments are considered to be 5 homework. To avoid any possible cheating problems, you must not do homework or home assignments, or write laboratory reports with any one else. Not limited to, but, any of the following constitute cheating: 1. Giving or receiving any written information about solution of any home assignment, 2. Transcribing solution of an assignment, 3. Using solutions of home assignments which were not done by the user (like last year's homework solutions done by someone else), 4. Giving or receiving any information or materials during exams, including printed materials, pencils, calculators, erasers, etc., 5. Talking in the exams, even if it is not related with the exam, 6. Looking over someone else's exam paper during exams, 7. Using any materials that are not allowed in an exam, 8. Any other acts considered to be cheating, plagiarism or falsification by the University regulations. Some of these acts are given in the university catalog. It is your responsibility to know and understand these acts. To deter and prevent cheating during exams, open or hidden video and/or tape recorders may be used. You will not be told whether or not the exam is being recorded and/or taped. Q. Cell Phone Use Cell phone use is not allowed in class rooms. You must turn your cell phone off unless you are expecting an emergency call. You need to get my permission to leave the phone on (vibrate only). One point shall be deducted from your overall average for each disturbing call you receive or each time I see you playing with your phone. R. UMES Zero Tolerance Policy The University of Maryland Eastern Shore maintains and strictly enforces a policy of zero tolerance with regards to fighting, the use, possession and/or distribution of illicit drugs, and the possession of dangerous weapons, firearms, and explosives. If a student is found guilty of using, possessing, selling or distributing illegal drugs; initiating a fight, or using any object (weapon) with the intent to cause harm, the minimum sanction will be suspension from the University for one (1) academic semester, and where appropriate will be referred to local policing authorities for criminal prosecution. Suspension from the University for a violation of the zero tolerance policy will result in the cancellation of the accused student’s housing contract, lost of tuition and fees, grades attempted, and denial of a housing contract in the future. If a student is found guilty of drug distribution or the possession of dangerous weapons, firearms, or explosives, the maximum sanction may result in expulsion from the University. 6 STANDARDS FOR HOMEWORK, PROJECTS AND TESTS Effective communication is an important part of engineering. A correct technical result that is poorly communicated is often no better than one which is incorrect. To emphasize this fact, consideration of effective communication will be given in grading homework, projects and tests. Anything which seriously detracts from ease of understanding of your work can result in a loss of points. Illegibility will be considered as serious fault for which points will be deducted. Homework and Project Standards Your written homework and projects will be judged according to a recommended standard. Each Homework problem will be treated as a formal engineering assignment. Give table or/and figure numbers when data is taken from them. Interpolate approximately on tables unless exact interpolation is required by the problem statement. Write as clearly and as explicitly as possible, results and solutions shall not be guessed. Use only one 8.5 x 11 in size paper, and put your initials on each page. A title page should be added to each assignment. Title page should contain: (a) Course number and name, (b) Homework set no, (c) Problems submitted. (d) Due date, (e) Submission date, (f) Days late, (g) Your full name, and (h) Grade. Staple your assignment at the left hand upper corner and DO NOT FOLD IT. You may use files for the projects. A sample title page is enclosed you may copy and use it. The solution for each problem should contain: (a). Problem statement, (b). Sketch and/or diagram, (c). Analysis and results (if lengthy, summarize results in body of report, with details in appendix), (d). Discussion and conclusions when applicable. For table and figure notations follow the same form given for the figures and tables in your textbook (i.e. table number and title at top for tables, figure number and title at bottom for figures). 7 Test Standards No specific form standard can be given for tests since they may vary greatly and the student is under time pressure. For this reason it may be necessary, also, to overlook minor errors in spelling, punctuation, or grammar. It is to your own benefit, however, to communicate your knowledge to the grader as well as you can. With this in mind, you should practice effective communication techniques during tests. Occasionally points may be deducted for unnecessarily poor communication. To avoid this, you should follow the following rules: (a). Small size blue books shall be supplied (b). Put problem solutions in numerical order. Put problem numbers on every other or three pages (depending on the number of problems in the test) of your blue book. Start with the first one and go on in increasing order. Now you are ready to start answering any problem you like. Write the answers in the reserved section of your blue book for the problem you have started. (c). Bring the supplemental materials (tables, charts etc.) distributed in the class. No charts, tables, equations etc. shall be supplied during exams. (d). Always use more detailed charts and tables. Most of the time distributed charts and tables are more detailed. (e). Write your name and course name on the blue book. If there are any loose sheets, put your names on each of them, (f). Write clearly and legibly, no guessing is allowed when grading the exams, (g). State important assumptions clearly, (h). Flag important results by underlining or boxing (i). If the solutions should be excluded from grading, cross it out clearly and completely, (j). Give only one solution. Otherwise, first solution shall be accepted as the answer to the question. (k). Use the closest entry on the tables, do not interpolate unless it asked to interpolate, (l). Be as accurate as possible when reading charts. 8 ETME 301-THERMODYNAMICS AND HEAT POWER HOMEWORK NO : PROBLEM NO'S : CHAPTER NO : DUE DATE : SUBMISSION DATE : SUBMISSION HOUR : LAST 7-DAYS’ STUDY TIME: DAYS LATE : NAME : GRADE : 9 ETME 301 - THERMODYNAMICS AND HEAT POWER HOMEWORK SETS (Alternate Set) Unless otherwise replaced, modified or due dates are changed, the following are the homework sets. Due hour is just before class starts. Sets assigned for the exam weeks must be turned in on time. No late sets shall be accepted for exam weeks. If you enter "Days Late" incorrectly, penalty will be 5 points per wrong-day. Homework is one day late if it is not on instructor's desk when I enter the classroom. YOU MAY STUDY TOGETHER, BUT, SOLVING HOMEWORK PROBLEMS TOGETHER IS NOT ALLOWED. Homework is for you to do it at home so that you can test yourself and study. Same rules apply to laboratory reports.

Saturated steam at 1000 psia is expanded through first stage of the turbine. Part of saturated steam is bypassed to the feed water heater as shown in diagrams given in computer program for Rankine cycle. Condenser pressure is 1 psia. Assume turbine and pump efficiencies are .85, .8, .9, and .95 respectively. You may have to magnify your y-axis on some plots to see the peak (i.e. you may plot efficiency between 25 to 35%). Using computer program THERMO located on some computers. Use at least 6 points. To locate the peaks accurately, you may have to use more points. Obey table and graph formatting rules (table and figure numbers, table/figure titles, axes titles and units, etc.). Use Excel to create your graphs. Show the data you have plotted in table form also. (15) (a). Sketch schematics of power plants and T-s diagrams for both closed and open feed water heaters, (15) (b).
