INTRODUCTION

Open-ended experiment employs out-come based education. It is a student-centered learning

philosophy that focuses on empirically measuring student performance, which is called outcomes.

Thus, in this open ended laboratory project, a problem will be given to a group of student to solve

or complete by conducting certain experimental work within a specified time. Student should

actively participate in discussion either in or out lab class.

EXPECTED OUTCOME

• A LAB SHEET for the newly developed experiment that consist of all standard content of Thermodynamics Lab Sheets

• Fully functioning EXPERIMENTAL TOOLS to conduct the experiment.

• FULL REPORT for the newly developed experiment

• A PRESENTATION SLIDE that explains newly developed experiment.

ACTIVITYWEEK ACTIVITY

2 or 8 Students will be divided into small group and each group consists of 4-5 students. Each group is required to propose their open ended laboratory project based on title/scope given by the instructor

3 or 9 All groups are expected to come up with their Title, Learning Outcomes, Objectives, Skills, Materials, Scopes, Theory and Procedures of the new experiment setup for experiment. The proposal must be approved by the Lab Instructor while the technical aspect must be approved by the Lab Assistant Engineer

4 or 10 Do an experiment and construct lab/experiment instruction.

5 or 11 Produce experiment full report 1.

6 or 12 Do an experiment and construct lab/experiment instruction. Produce experiment full report 2.

7 or 13 Project presentation 1 or 2.

MARCET BOILER, CLAUSIUS-CLAPEYRON EQUATION

TOPIC LEARNING OUTCOMES

At the end of this topic, students will be able to:

1. shows that when three non-parallel forces in the same plane are in

equilibrium, their line of action meet at a point.

2. shows that the resultant of two forces can be found using the

Parallelogram of Forces.

3. Apply Newton’s Law of Motion to determine the resultant forces.

Topic 1: EXPERIMENTAL EQUIPMENT

INTRODUCTION

In this experiment, water is heated up

under constant volume. During the

phase-change process, pressure and

temperature are dependent properties,

having a definite relation between them.

The characteristic of the relation is shown

in Figure 1.1.

THEORY

After all liquid has evaporated, the temperature rises, and the water now will

be in the vapor phase. The heat added from the liquid state to boiling, the

phase change and the result of adding more heat can seen from the phase

diagram in Figure 1.2.

Clausius-Clapeyron equation

Result

RESULT (15%)

a. Complete the data sheet provided in Appendix.

b. Complete the data sheet provided in Appendix by calculating

the ΔTΔp / and dp/dT using Equation (1) for each measurement.

For the dp/dT calculation, use steam table and make

interpolation where necessary.

c. Plot ΔTΔp / versus dp/dT. Compare the deviation between both values and

state your explanation about this difference.

Topic 2: TWO-STAGE AIR COMPRESSOR

TOPIC LEARNING OUTCOMES

At the end of this topic, the students will be able to:

• Understand the polytropic process in the two-stage air compressor.

• Determine of the polytropic efficiency of a compressor.
