B. Procedure: (with attached photos)
1. Measure the air tunnel, especially the orifice diameter.
2. Start the motor of the centrifugal fan. Make simultaneous readings on the manometer, current on
the Amprobe suction and discharge temperature, and the speed using the tachometer.
3. Use two minutes duration for each trial.
4. Compute the necessary requirements needed to complete the data
E. Conclusion
The experiments let us, the students, to practice and demonstrate on how the velocity of air
change depending on the area of the duct. This also enables us to understand the proper use of the
instruments. The experiment also implies the importance of Bernoulli’s concept related to the flow rate of
air. There are also significant effects in the temperature and pressure over time.
