ME 200 – Thermodynamics I Name: Naik Sameer Fall 2009 (Last) (First) Thermo Number: 1000 CIRCLE YOUR LECTURE BELOW Div. 1 – 8:30 am Div. 2 – 10:30 am Div. 3 – 1:30 pm Naik Lucht Mongia Div. 4 – 3:30 pm Div. 5 – 7:30 am Kim Hess EXAM 3 INSTRUCTIONS This is a closed book and closed notes exam . Answer as many questions as you can in the allotted time. Do not hesitate to ask questions if you do not understand a problem statement. For your own benefit, please write clearly and legibly. Maximum credit for each problem is indicated below. To receive full credit for a problem, you must follow instructions, show all work, and write the answers in the appropriate boxes. For Problems 1 and 2, significant credit will be given if you start with the basic equation(s), list all assumption(s), and illustrate the method by which you propose to solve the problem correctly. Some parts of Problem 3 will be given no partial credit. Do not write on the back of any page. Material on the back of a page may not be graded. If additional pages are needed, ask for additional pages. Insert the extra pages in their proper order and staple them to the exam. The use of PDAs, Blackberry-type devices, cell phones, laptop computers, or any other sources of communication (wireless or otherwise) are strictly prohibited during examinations. Doing so is cheating. If you bring a cell phone or other communication devices to the examination, they must be turned off prior to the start of the exam, placed in your backpack, and the backpack stored below your seat , and only picked up as you leave the examination room for the final time. They are not to be turned on again until after you have exited the examination room. Otherwise it will be considered a form of cheating and treated as such.

Name: Naik Sameer Thermo No: 1000 (Last) (First) Problem 1: (30 points) Given: Saturated liquid water at 200 C (state 1) is expanded inside a piston-cylinder device via an internally reversible, isothermal (constant temperature) process. The pressure inside the cylinder at the end of expansion is 10 bar and the temperature is 200 C (state 2). Find: (a) Show the process from state 1 to state 2 on P - v and T - s diagram in relation to the vapor dome. You must show the appropriate lines of constant pressure on both diagrams. Indicate the work and heat transfer during the process on P - v and T - s diagram, respectively. (10 points) (b) What is the heat transfer per unit mass (kJ/kg) during the expansion process from state 1 to state 2? (6 points) (c) Calculate the work per unit mass (kJ/kg) during the expansion process from state 1 to state 2.
