Ifyou have any questions about the readings or the class in general, ask the instructor. I am yournumber one resource for success in this class. Come to my office or make an appointment, and wewill talk about your problem. It is better to do so before things get out of hand -- not after the fact.It is your responsibility to participate in your learning. Learning is not a spectator sport. It will taketime (minimum of 8 hours per week for this course), effort, work, and involvement. You must readyour assignments before class, note what you do not understand, actively seek answers to what youdo not know. You should ask questions in class or during office hours or of other students, studybeyond the minimum text assignments by searching course references. You must apply what youlearn to solve homework problems before the due date and ask for help when you need it. You shouldstudy on a regular basis and not cram for tests, participate in class by being actively involved indialogue with your classmates and instructor, think about what you are learning, and apply what youhave learned to solve other related problems. Arriving late, leaving early, chatting with yourneighbors, doing your other homework, or having beepers and cellular phones turned onduring class time are behaviors unacceptable in this class. These behaviors are extremelydisrespectful to your fellow students and your professor. It is ultimately you who is responsible foryou success in this class, not the instructor, not your fellow students.

No late homeworkwill be accepted. Not all of the assigned problems will be graded, but you will not know in advancewhich will be graded, so it is best to do them all. An engineer's work should be neat, well organized,and easy to follow. You are expected to follow this standard format for completing chemicalengineering problems. Points may be deducted for work that does not adhere to this format. Anexample of homework format is given below:______________________________________________________________________________CHE426 Problem set #1 NGUYEN, THUAN 1/11. A thermometer having a time constant of 1 min is initially at 50oC. It is immersed ina bath maintained at 100oC at t = 0. Determine the temperature reading at t =1.2 min.SolutionThermometer with τ=1 minLet x =bath temperature, y = indicated temperature ys = 50oCY = y(t) – ys = y(t) – 50X = x(t) – xs = x(t) – 50( )( )Y sX s = ( )11st + = 11s +X(t) = 50u(t)  X(s) = 50/s  Y(s) = 50s11s +  Y(t) = 50(1 – e-t)Y(1.2) = 50(1 – e-1.2) = 34.9oC  y(1.2) = Y(1.2) + 50 = 34.9 + 50 = 84.9oCThe thermometer reading is 84.9oC at t = 1.2 minHow you get your answer is very important in engineering, therefore show all of your work onassignments, quizzes, and exams. Mark your final answer clearly by drawing a box around it, and besure to include the units! Except for the questions that require you to fill in the blank, no credit willbe given for final answers that do not show the work involved. Staple all pages of an assignmenttogether in the upper left corner. To facilitate and reward attendance and participation, we will use an electronic studentresponse system from i>Clicker.
