Unformatted text preview: Lab Report # 5 Bo Sang Yun (lab partner : Tae Sung Kim) 1. I nt roduction 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 ambient pressure at A is small....
