Challenge Problems
Push your limits with challenges.
Question 1
A glass capillary tube has a radius of 0.003 m. Calculate the height to which water will rise in it if the surface tension of water is 0.072 N/m and the density of water is 1000 kg/m³.
💡 Hint: Ensure to apply the correct values and use cos(θ) as 1 if it is not stated otherwise.
Question 2
Explain how capillary rise can differ in two capillaries of the same radius but with fluids of different surface tensions.
💡 Hint: Consider comparing water and oil under similar conditions.
