Challenge Problems
Push your limits with challenges.
Question 1
Given a capillary tube of diameter 2 mm, calculate the height the water will rise if the surface tension is 0.072 N/m and the density of water is 1000 kg/m³.
💡 Hint: Focus on calculating the effective radius from the diameter.
Question 2
If a tube has a contact angle of 30 degrees with water, how would this angle affect the height of rise compared to a 0 degree angle in practical applications?
💡 Hint: Consider how angles influence capillarity in real-life scenarios.
