2.4. Summary of Pressure Difference

Try these first

1. 1.

   What is the definition of laminar flow?

   Hint

   Think about how layers of a deck of cards slide over each other.

2. 2.

   Calculate the discharge if 5 kg of water at a density of 1000 kg/m³ is collected in 10 seconds.

   Hint

   Remember to convert mass to volume using density.

3. 3.

   What defines laminar flow?

   • Smooth flow with layers
   • Chaotic mixing of fluids
   • High turbulence

   Hint

   Think about multi-layer cake icing.

4. 4.

   True or False: The Reynolds number greater than 2000 indicates laminar flow.

   • True
   • False

   Hint

   Recall the threshold for laminar versus turbulent.

5. 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.

   Hint

   Keep your calculus and integration in check!

6. 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.

   Hint

   Understand how temperature affects liquid properties.
