Turner, Fundamentals of Thermal-Fluid Sciences, McGraw-Hill, 2001.Course Goals: ME 300 contributes to the following four ME Program Outcomes. The specificperformance measures supporting the program outcomes are listed following each outcome.OUTCOME 2b: Appreciate the role of thermodynamics in engineering and society. Understand the importance of thermodynamic properties and know how to use them. Understand the First Law of Thermodynamics and know how to use it to solve engineering problems Understand the Second Law of Thermodynamics and know how to use it to solve engineeringproblems.OUTCOME 2e: Apply the First and Second Laws to practical systems, including Rankine cycles, refrigeration cyclesand gas cycles.OUTCOMES 5e and 5g: Develop fundamental engineering problem solving skills.

Instructor’s Mission: My mission is to aide students in learning and motivate them to become premiereengineers, scientists, and engineering technologists. My duty is to teach the student problem solvingskills and provide them with the proper skillset and required tools for which he/she will be successfulbeyond this class and beyond graduation. My interest lies with the learning process of the student and tomake the course interesting and enjoyable. I want to be approachable and available. Therefore, I stronglyencourage students not to hesitate to come to my office if they are struggling in this class or any otherclass. Please come if you are doing well, too.Course Attendance: Class attendance is strongly encouraged.Academic Integrity: Academic integrity is the pursuit of scholarly activity in an open, honest andresponsible manner. Academic integrity is a basic guiding principle for all academic activity at ThePennsylvania State University, and all members of the University community are expected to act inaccordance with this principle. Consistent with this expectation, the University's Code of Conduct statesthat all students should act with personal integrity, respect other students' dignity, rights and property, andhelp create and maintain an environment in which all can succeed through the fruits of their efforts.Academic integrity includes a commitment not to engage in or tolerate acts of falsification,misrepresentation or deception. Such acts of dishonesty violate the fundamental ethical principles of theUniversity community and compromise the worth of work completed by others. The instructor mayassign an academic sanction ranging from a warning, to failure on an assignment or in the course, or toremoval from the course. (Policies and Rules for Students, Section 49-20, and Academic IntegrityProcedure G-9.)Students with Disabilities: Penn State welcomes students with disabilities into its educational programs.If you have a disability-related need for modifications or reasonable accommodations in this course,please contact the Health & Wellness Center, Disability Services, located in the Sheetz Family HealthCenter. For more information, call (814) 949-5540 or visit the Disability Services web site atwww.altoona.psu.edu/healthwellness. Your instructors should be notified as early in the semester aspossible regarding the need for modifications or reasonable accommodations.Homework Format: Submit homework on engineering or notebook paper with no tears. Also, only useONE side. Problems on the backside will not be graded. Please include the homework cover page andwhere applicable follow the handout with the homework format for engineering problems. Theprescribed format strengthens logical methodology and systematic analyses for solving engineeringproblems. At least ONE randomly chosen problem of the assigned homework problems will be graded.Course Website: The course website is in the ANGEL (www.angel.psu.edu) system. Please verify thatthe email address listed in the Angel website is the one that you regularly use. The course website will beused to post assigned homework, homework solutions, announcements, and other additional informationpertaining to the course.Make-Up Exams and Homework: There will not be any make-up exams, quizzes, or homework unlessabsolutely necessary and must have the instructor’s approval prior to the exam, quiz, or homework andmust follow university policies.Class Cancellation: In the event that snow or other inclement weather forces a delay or a closing of thecampus, class may be cancelled and a notice will be posted on Penn State Altoona’s Website(www.aa.psu.edu). Additionally, for other foreseen or unforeseen class cancellations, notification will beposted on the class website or an email will be sent out to students in the class. You may also contact meby phone whether or not class is indeed cancelled.

Grading: The following breakdown is the tentative percentage distribution the semester. There will betwo mid-term exams, 7-9 quizzes, and a comprehensive final exam. Your lowest quiz score will bedropped, accounting for 16% of your grade. There will be 7-9 homeworks assigned and the two lowestscores will be dropped, constituting 16% of your overall grade. No homework will be accepted late. Atleast one problem will be graded and returned. Scheduled mid-term examinations will contribute to 48%of your grade in this course. Exam problems may consist of short answer, fill in the blank, and/orproblem solving. A comprehensive final exam, during finals week, will count for the remaining 20%.FINAL EXAM conflicts must be filed in advance according to university policies. Also, it is possiblethat mid-term exams and the final exam may be conducted at a common time for both sections.Midterm Exams (3) 48%Quizzes 16%Homework 16%Final Exam 20%BE ADVISED THAT ME 300 IS A C-REQUIREMENT COURSE. A MINIMUM GRADE OF C ISREQUIRED FOR THE COURSE FOR YOUR BACCALAUREATE DEGREE PROGRAM.Tentative Class Schedule: The following table consists of a tentative course schedule for the semester,some dates may change.Class # Date Topic Description Reading Due1 Jan 9 (Mon) course introduction and preliminaries 1.1-1.22 Jan 11 (Wed)physical framework, types of systems, conservationprincipals1.3-1.43 Jan 13 (Fri) definition of properties, states, cycles, equilibrium 1.5Jan 16 (Mon)Martin Luther King Day – NO CLASS4 Jan 18 (Wed) dimensions; units; problem solving methodology 1.6-1.8 QUIZ#15 Jan 20 (Fri) common thermodynamic properties 2.1-2.2 HW#16 Jan 23 (Mon) calorific equation of state, enthalpy, specific heat ratios 2.2b7 Jan 25 (Wed) state principal; equation of state, entropy 2.3-2.48 Jan 27 (Fri) Gibbs free energy, ideal gas law 2.4d QUIZ #29 Jan 30 (Mon) P-v-T relationships, phases, quality 2.5 HW#210 Feb 1 (Wed) pure substances; P-v; T-v diagrams 2.611 Feb 3 (Fri) EXAM #112 Feb 6 (Mon) multiphase substances; phase boundaries; compressibility 2.713 Feb 8 (Wed)Letter Grade ScoreA 93-100A- 90-92B+ 87-89B 84-86B- 80-83C+ 76-79C 70-75D 60-69F < 60multiphase substances (cont’d); linear interpolation; inclassproperty exercise2.8
