Question 1.
What is the definition of laminar flow?
Show hintHide hint
Think about how layers of a deck of cards slide over each other.
Question 2.
Calculate the discharge if 5 kg of water at a density of 1000 kg/m³ is collected in 10 seconds.
Show hintHide hint
Remember to convert mass to volume using density.
3Question 3.
What defines laminar flow?
- Smooth flow with layers
- Chaotic mixing of fluids
- High turbulence
Show hintHide hint
Think about multi-layer cake icing.
4Question 4.
True or False: The Reynolds number greater than 2000 indicates laminar flow.
- True
- False
Show hintHide hint
Recall the threshold for laminar versus turbulent.
Question 5.
Given a water flow scenario through a pipe with specified viscosity and length, determine the pressure difference when water is flowing at varying discharge rates.
Show hintHide hint
Keep your calculus and integration in check!
Question 6.
Analyze and calculate the impact of temperature change on the viscosity of crude oil and how it influences the pressure difference in different pipe sizes.
Show hintHide hint
Understand how temperature affects liquid properties.
