Challenge Problems
Push your limits with challenges.
Question 1
A thin glass column is used to measure the height of water (surface tension = 0.0728 N/m). The diameter is 2mm. Calculate the height to which water will rise in the column.
💡 Hint: Convert diameter to radius and ensure unit consistency.
Question 2
In a situation where two different liquids are involved, how would you approach calculating the equilibrium height in a shared capillary tube?
💡 Hint: Start by establishing the individual contributions of both fluids before combining them.
