Is Bernoulli's Principle Effective?

Is Bernoulli's Principle Effective?

Jimmy Kurtz

Question: My question was if that the Bernoulli Principle actually worked and if it was effective.

Hypothesis: My hypothesis was that the faster and hotter the air, the higher the ping pong ball went.

Procedure

  1. Turn on hair dryer

  2. Switch to what setting I was testing

  3. Measure how high the ball went in the air

  4. Repeat for a total of 3 times

  5. Find average

Conclusion

In conclusion, my hypothesis was right about how the hotter and faster the heat gets the higher the ball goes. I believe that if I didn’t do my project fairly things have could of gone way differently. For instance, if I hadn't measured right, that could throw off the whole project. Another example, is that if I hadn't used the same ping pong ball. The ball would of weighed more. I could have improved my project by doing more testing. If I did that, I could have gotten a lot more of data which would have gotten me more fair numbers.

Abstract

February 8, 1700, Daniel Bernoulli was born. He was a mathematician and physicist. Bernoulli is most recognized for his principle named after him. And I decided that I would test his principle. The Bernoulli Principle states that for an in viscid flow of a non-conducting fluid, an increase in the speed, the less pressure it exerts. For instance, I used the example of the ping pong ball being pushed in the air with the fast air coming from the blow dryer. I tried to see if different heat and speed settings would change how high the ball went. I hypothesized that the hotter and faster the air the higher the ball goes.

I first started my testing on the lowest heat and slowest speed setting. The ball went only 2 inches in the air. I then repeated it two more times and got an average of 1.7 inches. Next, I tried it on the medium heat and speed setting. The ball then went about 4.2 inches in the air. Again, I repeated it two more times and got an average of 4 inches. Finally, on the hottest heat and speed setting, the ball went in a total of 6 inches. And for the last time I repeated it two more times and got an average of 7 inches. Then, I needed to find the overall average height of the ping pong ball throughout my whole experiment . The average height of the ball was 3.9 inches. In summary, I found that the hotter the heat gets the higher the ball goes.

In conclusion, my hypothesis was right about how the hotter and faster the heat gets the higher the ball goes. I believe that if I didn’t do my project fairly things have could of gone way differently. For instance, if I hadn't measured right, that could throw off the whole project. Another example, is that if I hadn't used the same ping pong ball. The ball would of weighed more. I could have improved my project by doing more testing. If I did that, I could have gotten a lot more of data which would have gotten me more fair numbers.
