LABORATORY REPORT
1. Experiment OutcomeThermodynamic is a basic engineering
science course that introduces and applies fundamental concepts of
thermodynamic. Thermodynamic is the study of work, heat, and
energy, and the rules whitch govern how each of these is
transformed into the others. The course explores relationship
between properties of matter and basic laws of thermodynamics,
which are fundamental laws of nature governing the behavior of all
physical systems, Mathematical model of these physical laws are
presented and applied to systems involving pure compressible
substance. These principle are used to analyze energy conversion
process, cycle, devices and systems. Economic, environment,
sustainability and political implications are discussed to provide
a context for the technical material.
2. TheoryThe main distinguishing property of gases is their
uncanny ability to be compressed into smaller and smaller spaces.
Gases are also the least complex state of matter. The ideal gas law
relates temperature, volume, and pressure, so that we can calculate
any one of these quantities in terms of the others. Gases are
easily expandable and compressible unlike solids and liquids. Gases
have a measurement of pressure. Pressure is defined as force
exerted per unit area of surface. It can be measured in several
units such as kilopascal (kPa), atmosphere (atm), and millimeters
of Mercury (mmHg). Gas has alow density because its molecules are
spread apart over a large volume. A gas will fill whatever
container that it is in.
3. Apparatus/Equipment TEPGC unit SCADA-TEPGC program
Compression tank (large) Depression tank (small)
4. Safety Precautions 4.1 Make sure the student follow the
laboratory or workshop safety regulators.4.2 Experiment must be
conduct by lectures or experience lab assistance.
5. Safety Precautions 5.1 Connect the interface and execute the
SCADA-TEGPC program, supplied with the equipment.5.2 Place the
valves in order to the air pump is supplied with the external air
and pressurizer the larger pressure tank. When the air is filled
with the external air, close the valve.5.3 Click START in the
program and change the file name for the practice and click the
ACTUATORS button.5.4 Select the time for 15 second for the practice
and 5 second for the second practice.5.5 Click on TAKE DATA button
to start collecting data.5.6 Take the reading of initial
temperature and pressure. Estimate how much the data we want to
collect for 15 second and 5 second.5.7 Press on the ST1 button. The
press on the SP1 button.5.8 When the data have been taken, click
DONE button. Then, click QUIT button to exit the program5.9 After
the program closed, click WINDOW button and search for COMPUTER
button.5.10 In COMPUTER folder, search for OC storage. In the OC
storage, search for TEPGC folder.5.11 Search for the file that we
save at the initial process from the practice. Note the data to
make the analysis of the process.
7. DiscussionThe data between the two experiment exactly the
same because the time given to calculate the data are same. The
higher the volume of gas the higher the pressure recorded.
8. ConclusionIn conclusion, this experiment need to be done
twice or more to get the exact data and avoid error reading.
