Question 1.
What is shear stress in fluid mechanics?
Show hintHide hint
Think about forces and area.
Question 2.
What characterizes a turbulent flow compared to laminar flow?
Show hintHide hint
Consider the motion patterns of fluid.
3Question 3.
What does the velocity defect law primarily describe?
- The relationship between velocity and turbulence
- The difference between maximum velocity and actual velocity
- The density of fluid varying with temperature
Show hintHide hint
Think about the scenario when fluid flows through a pipe.
4Question 4.
Turbulent flow typically has which type of velocity profile?
- True
- False
Show hintHide hint
Refer back to what we discussed regarding velocity profiles.
Question 5.
A cylindrical pipe has a radius of 0.05 m and a shear stress at the wall of 50 N/m². Calculate the frictional velocity and discuss the implications of this value on flow rate.
Show hintHide hint
Use the given shear stress to find the relation.
Question 6.
Discuss the effects of reducing surface roughness in piping systems in terms of turbulent flow efficiency.
Show hintHide hint
Consider how rough surfaces affect flow interaction.
