Question 1

What does dimensional homogeneity ensure in fluid mechanics equations?

  • All units are consistent
  • Variables are unrelated
  • Calculations are random

💡 Hint: Think about what happens if units don't align.

Question 2

True or False: Reynolds number is dependent on dimensional units.

  • True
  • False

💡 Hint: What does it mean to be 'dimensionless'?

Challenge Problems

Push your limits with challenges.

Question 1

You want to design an experiment on the drag force acting on a sphere in water and air. Define the parameters, outline the steps for dimensional analysis, and determine what dimensionless groups would be necessary.

💡 Hint: Think about how these variables relate to one another in fluid flow.

Question 2

Given a scenario where a pipe diameter increases, resulting in turbulent flow, suggest a method for determining the new Reynolds number and anticipating changes in fluid behavior.

💡 Hint: What do you already know about how flow transitions from laminar to turbulent based on Reynolds number?
