Lab - Bernoulli's Equation Applied To A Convergent- Divergent Passage

Questions for Further Discussion -

1. What boundary layer thickness do your results lead you to expect. Can you infer this from the graph of Figure 4.5?

2. What is the Mach number at the throat of the duct? For approximate calculation, you may assume that the static pressure and temperature there are approximately the same as in the airbox. The air velocity at the throat may be found from the Pitot-static reading, and the acoustic velocity may be estimated from the equation a = √(γRT).

3. What difference to the results would you expect if the flow direction were reversed? You ma y check your prediction by reversing the liners.

4. What suggestions have you for improving the experiment?

5. How might you check whether there is in fact a boundary layer of significant thickness at exit from the duct? A possible project would be to devise and construct a suitable simple traversing gear from a Pitot tube which would measure the velocity distribution. Would it be necessary to traverse along more than one axis?

Use the provided Bernoulli experiment data to generate your individual report for lab. Your Lab Report Must be in the format of the AFMC paper.

The following sections need to be included in your paper:

1. Title and Abstract

2. Introduction

3. Experimental techniques

4. Results

5. Discussion

6. Conclusion

7. Bibliography

You should also integrate responses to questions 1-5 into your discussion (do not answer these questions in dot-point format!).
