1993 Catalog Data:        14-650-433: Mechanical Engineering Laboratory II (1)

                                        Prerequisite: 14-650-282; 312; 350

Comprehensive experiments in fluid dynamics, heat transfer, acoustics power system, and dynamic mechanical systems. Preparation of test procedure, data analysis and presentation of reports and conclusion.

Textbook:                       None

Coordinator:                   K.T., Rhee, Associate Professor of MAE

Goals:                             The objectives of this course are twofold:

to give the students the opportunity to test the theoretical knowledge on thermodynamics, heat transfer and and vibration with experiments, and to permit the student to deliver a technical presentation on laboratory results to their classmates in a formal manner.

Prerequisites by Topic:

1. Thermodynamics and heat transfer

2. Mechanical measurements

3. Fluid mechanics

Laboratory Projects: Report required for each experiment by every individual.

1. Measurement of the NTU. Use a counter-flow heat exchanger and compare with its theoretical value. Explain any discrepancy (three weeks).
2. Shock wave propagation speed. Learn how to use instruments to determine the propagation speed of the shock and compare the results with computed values (three weeks).
3. Single degree of freedom vibration. Measure the natural frequency of a one degree of freedom mass-spring system to compare with the calculated value. Use a fast data acquisition system and learn to transfer the data to an on-campus computer for subsequent analysis (three weeks)
4. Air conditioning experiment. Learn the subunits composing the entire air conditioning system by measuring important numerical values for evaluating their performances (three weeks).
5. Oral presentation of Laboratory results. Learn and practice the formal technical presentation by following major steps of preparation, including making visual aids and graphic materials for effective delivery of a talk.
