Challenge Problems
Push your limits with challenges.
Question 1
You have a capillary tube with a radius of 0.01 m. Calculate how high water will rise if the surface tension is 0.072 N/m and density is 1000 kg/m³.
💡 Hint: Remember, density and acceleration due to gravity are involved.
Question 2
Consider a fluid system where the upward force is 1.5 N and the downward force is 1.2 N. What needs to occur for equilibrium?
💡 Hint: Think about how forces can be adjusted.
