What is the Reynolds number threshold for turbulent flow?
Remember, it dictates flow types!
Name the two components of shear stress in turbulent flow.
Recall what differs from laminar to turbulent!
At what Reynolds number does turbulent flow typically occur?
Remember where turbulence starts.
True or False: Turbulent shear stress is only due to viscous shear.
Consider what adds to the total stress in turbulent flow.
A river has an average velocity of 3 m/s, and the width is 50 m with a depth of 2 m. Calculate whether the flow is laminar or turbulent.
Use Q = A*V to find velocity and check Re to classify.
Examine a scenario in which high turbulent flows lead to increased erosion along a riverbank. Analyze why turbulent conditions can exacerbate wear on the riverbank structure.
Consider energy and force application in taxiing conditions.
