which is only valid for nonturbulent flow.
Bernoulli’s principle also states that fluid is incompressible.
We did this with the use of an air
tube with two different diameters at each end, two manometers, a pitot tube which allowed
the measurement of the stagnant and ambient pressure, and an inlet attachment which is used
to cause turbulence.
Hypothesis:
Due to the use of the air tube and the manometers we should see that no
matter what values are found the equation will be proven, but once the inlet tube is inserted
there should be an error in B
ernoulli’s equation
due to turbulence.
Conclusion:
When calculating
∆𝑃
???𝑔
the value recorded was 0, which was expected
due to the fact that velocity was not supposed to change.
So with this value brings us to the
