This document outlines the procedures and expectations for laboratory experiments in Mechanical Engineering (ME) at a university. It discusses 1) safety rules that must be followed, 2) the organization of students into groups that will rotate through different experiments, 3) requirements for submitting experiment reports and files, and 4) the grading system. Students will be divided into groups to complete a series of experiments on topics like engines, pumps, and thermodynamics. Thorough lab reports must be submitted on time following a standard format.

1. 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.

2. 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 Power
ME 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

3. 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 into
four groups. Each group will be assigned specific experiment to be performed. The
groups will switch experiments until all groups were able to accomplish each of the
experiments.

SUBMISSION OF EXPERIMENT PAPERS:
All experiment papers should be converted to PDF files following the standard
experiment format. Pictures of the procedures should be attached to the experiment
paper.

4. Each folder in the experiment should contain a short video presentation of step by
step procedure done in the experiment. It should clearly show how each data are
gathered.

LABORATORY EXPERIMENT PAPER:
Laboratory experiment paper is a self-contained document wherein anyone with a
minimal background in Mechanical Engineering can duplicate the data gathered in
the 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.

5. 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-up
VI. 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:

6. 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 experiment
paper 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 excuse
letter is required to be submitted before the next meeting, and a schedule for his/her
missed experiment must be arranged and approved by the instructor. He will also be
required to perform his missed experiment individually.
