Challenge Problems
Push your limits with challenges.
Question 1
A liquid has a surface tension of 0.071 N/m, flows with a velocity of 2 m/s, has a density of 800 kg/m³, and a characteristic length of 0.05 m. Calculate the Weber Number and analyze its implications for droplet formation.
💡 Hint: Use the formula correctly and reflect on the fluid dynamics principles involved.
Question 2
Describe how varying the surface tension of a liquid would affect the Weber Number and the behavior of a spray application.
💡 Hint: Consider how the forces interact when surface tension is altered.
