1.11. Problem on Laminar Flow

Try these first

1. 1.

   What is laminar flow?

   Hint

   Think about how a liquid would flow in a straight, even line.

2. 2.

   What is the Reynolds number used for?

   Hint

   Remember the number that helps you understand fluid behavior.

3. 3.

   What defines laminar flow?

   • Smooth
   • ordered flow
   • Chaotic flow
   • Flow with eddies

   Hint

   Think about what flow is revealed as steady and organized.

4. 4.

   Is turbulent flow characterized by laminar streamlines?

   • True
   • False

   Hint

   Consider the definition of each flow type.

5. 5.

   A fluid has a density of 1000 kg/m^3 and flows through a diameter of 10 m at 3 m/s. Given that its kinematic viscosity is 0.001 m^2/s, what is the Reynolds number and the nature of the flow?

   Hint

   Be careful with units when calculating.

6. 6.

   Derive the equation for velocity profile in laminar flow through a pipe, stating assumptions and integrating the necessary terms.

   Hint

   Focus on the fundamental equations for fluid flow.
