Challenge Problems
Push your limits with advanced challenges
Calculate the capillary rise of water in a tube with a diameter of 2mm, where the surface tension is 0.072N/m, the contact angle is 0 degrees, and the liquid density is 1000kg/m^3.
💡 Hint: Plug the values into the capillary rise formula and simplify.
Discuss how changing the surface tension and contact angle affects the height of fluid in various applications.
💡 Hint: Consider practical scenarios, like how different liquids behave in the same plant system.
