Lab Report # 5 Bo Sang Yun (lab partner : Tae Sung Kim) 1. Introduction In this experiment we use Bernoulli's principle, P a + ½ v ρ a 2 + gy ρ a = P b + ½ v ρ b 2 + pgy b , for fluids under certain conditions In this lab, we will observe the flow of air through a long tube and compare our observations with the predictions of Bernoulli’s law. First, diameters for each tube A and B will be measured, and stagnation and ambient pressures will be recorded. We will also see change in Bernoulli’s equation when energy is lost to heat due to friction under turbulent condition, since Bernoulli’s equation holds for incompressible, inviscid, and non-turbulent flow. Hypothesis : If fluid shows incompressible, inviscid, and non-turbulent characteristics, it obeys Bernoulli’s equation, P a + ½ v ρ a 2 + gy ρ a = P b + ½ v ρ b 2 + pgy b. 2. Conclusion The velocity of air at point A is bigger than that at point B, which means ambient pressure at A is small. Velocity at point B is smaller since ambient pressure at B is big. Thus, the difference in ambient pressure is bigger than that of stagnation

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
