ME LABORATORY REMINDERS: 1. “No Instructor – No Experiment” For safety reasons, no equipment will be operated for a laboratory class if the instructor is not present. This includes make-up classes that will require a permit from the LABORATORY IN- CHARGE. 2. All borrowers slip should be signed by the subject instructor and should be accompanied with the borrowers ID with the person name appears in the borrowers slip. 3. All damages and/or losses should be promptly reported. Damages and/or losses will be charged to the individual responsible. However, if the experiment is by group, charges will be equally divided among the group members unless special arrangements are made. 4. No item, tool, equipment or experiment manuals can be taken out of the laboratory premises without proper authorization from the LABORATORY IN-CHARGE. 5. No modifications, repairs of any equipment in the laboratory are allowed without written authorization from the LABORATORY IN-CHARGE. 6. Borrowing and returning of tools for non-ME laboratory subjects will be entertained only on the scheduled time. 7. SAFETY PRACTICES and RULES should be observed at all times.
ME LABORATORY SERIES:ME LABORATORY 1 ME Laboratory 1 deals with the familiarization of measuring instruments and devices used to measure pressure, temperature, viscosity, flow rate, area, etc. Last part of this subject deals with properties of fuels and lubricants. This subject will build the foundation for the next series of ME Laboratory subjects. Lists of experiments: Series 1: a. Pressure calibration b. Flash point and fire point of lubricants c. Laminar and Turbulent* d. Properties and Specific gravity of lubricants Series 2: a. Determination of area using Planimeter b. Velocity measurement using of pitot tube* c. Air flow rate and manometer reading d. Brake PowerME LABORATORY 2 ME Laboratory 2 deals with the study of machineries such as pumps, compressors, turbines, blowers and compressors. This subject also tackles refrigeration and ice making equipment.ME LABORATORY 3 ME Laboratory 3 deals primarily with diesel and gasoline engine familiarization, heat balance and efficiency. This subject also deals with hydroelectric power plant performance, boiler and steam power plants. Lists of experiments: Series 1: a. Engine Dismantling b. Bomb calorimeter** c. Friction losses in Bends and Fittings* d. Pumps in series and Parallel
Series 2: a. Refrigeration System b. Engine Heat Balance c. Pelton Turbine Efficiency d. Steam boiler familiarization**GROUPINGS:The class will be divided in two sections, and each section will be further divided intofour groups. Each group will be assigned specific experiment to be performed. Thegroups will switch experiments until all groups were able to accomplish each of theexperiments. M.E.

Pictures of the procedures should be attached to the experimentpaper.
Each folder in the experiment should contain a short video presentation of step bystep procedure done in the experiment. It should clearly show how each data aregathered. FILE NAME: 3MEB GROUP A Exp.

Series 1a (Engine Dismantling) (Engine Dismantling)Experiment papers will be submitted via e-mail at: email@example.comLABORATORY EXPERIMENT PAPER:Laboratory experiment paper is a self-contained document wherein anyone with aminimal background in Mechanical Engineering can duplicate the data gathered inthe experiment by simply following the step-by-step procedures written in it.Minimum Contents of Experiment Paper: I. Objectives of the experiment: The main objectives that you want to achieve in this experiment. It gives a brief description explaining what the group is doing and the things they are trying to find out. II. List of Equipments: Complete lists of equipments needed to perform the experiment.
III. Theoretical Background This part strengthens your hypothesis through research. This is the theory behind the experiment and this should be researched and briefly explained.IV. List of Nomenclatures: All the formula used in the experiment, variables and nomenclatures will be defined in this portion of the paper. List all measured quantities and methods of measurement. The values that are computed or given must also be present in this part of the paper.V. Procedures: This is detailed description of how the experiment was actually performed. Attach pictures of actual procedures done in the experiment. Include enough detail so that another group can duplicate the result with same or similar equipment. This part also includes the drawing of the system set-upVI. Experiment Results Clear presentation of final results of the experiment in tabular form or graphical form. A Graph of the parameters in x-y coordinates is also suggested to summarize the data in the table. This part shows the formulas, relations and computations used in the experiment.VII. Discussion This contains your groups’ interpretation of the experimental results along with any necessary justification. This part is where your group can discuss how some parameters in experiments affect the overall results. For example, by increasing the rpm of the fan, the volume flow rate of air also increased.VIII. Conclusion: This part wraps up the whole experiment if the objectives set in the first part are met during the experiment. Conclusion should answer the following:
o What have you proved during the experiment? o Is the experiment viable compared with the theory? o What are your realizations, observations and new insights learned during the experiment? o Do you have some recommendation to further improve the data gathering or expand more the leanings in the experiment? This is part where your group can also discuss areas or industry in Mechanical Engineering wherein you can apply the concept you proved in the experiment. IX. References: All references such as books, journals, websites etc. used in the experiment are all sited on this part.REQUIREMENTS:After performing the experiment, the group is required to submit the experimentpaper next meeting within the day. No late experiment paper will be accepted.Late experiments will have a grade of zero.When the member of the group is not able to perform the experiment, an excuseletter is required to be submitted before the next meeting, and a schedule for his/hermissed experiment must be arranged and approved by the instructor. He will also berequired to perform his missed experiment individually.GRADING SYSTEM: Experiment paper 30% Post Lab Exam 20% Group presentation 30% Final Project 20%
