Question 1
What is the primary purpose of boundary layer theory?
- To calculate fluid velocity in the center of a pipe
- To study the effects of viscosity and shear on fluid flow
- To explain wave dynamics
💡 Hint: Consider what influences the physical behavior of fluid near surfaces.
Question 2
True or False: The Reynolds number is only important at high flow velocities.
- True
- False
💡 Hint: Think about situations where flow might still be relevant despite lower speeds.
