Question 1.
Define the Reynolds number.
Show hintHide hint
Think about the forces acting on a fluid.
Question 2.
What flow regime is indicated by a low Reynolds number?
Show hintHide hint
Consider how fluids move smoothly versus chaotically.
3Question 3.
What is the function of the Reynolds number?
- To calculate flow rate
- To characterize flow type
- To measure fluid density
Show hintHide hint
Consider what influences the behavior of fluids in motion.
4Question 4.
True or False: A high Reynolds number always indicates laminar flow.
- True
- False
Show hintHide hint
Recall the connection between flow type and Reynolds number values.
Question 5.
A chemical engineer is designing a new pipeline system intended for a viscous liquid with a known viscosity of 0.005 Pa·s. The pipeline has a diameter of 0.15 m, and the liquid flows at 0.2 m/s. The density is 1200 kg/m³. Calculate the Reynolds number and determine if the flow is laminar or turbulent.
Show hintHide hint
Always check the flow regime after calculating.
Question 6.
You are tasked with improving the mass transfer efficiency in a water treatment plant. Identify the effects of increasing flow velocity and how it affects the Reynolds number and turbulence, thereby influencing mass transfer efficiency.
Show hintHide hint
Think about the physical forces at play in fluid movement.
