2 cards from this section. Quick, good the night before a test.
Define turbulent flow in your own words.
Think about how fluid moves in different flow regimes.
What is turbulence intensity?
Consider how fluctuations compare to steady flow.
What defines turbulent flow?
Think about the nature of turbulence versus smooth flow.
True or False: Shear stress in turbulent flow is typically lower than in laminar flow.
Reflect on how fluid dynamics differ in turbulent scenarios.
A turbulent flow in a pipe shows an average velocity of 5 m/s and an eddy size of 0.1m. Calculate the turbulence intensity if the root mean square of fluctuations is 0.25 m/s.
Use the formula for turbulence intensity carefully.
In a practical scenario, if the shear stress due to turbulence is measured at 150 N/m² while laminar shear is 30 N/m², what is the total shear stress, and what does this indicate about flow conditions?
Calculate total shear by adding both components together.
