SUMMARY

Meniscus formation in water occurs due to the interplay of adhesion and surface tension when a solid object is immersed in the liquid. The discussion highlights that the meniscus increases the effective free surface area of water within a tube compared to an unconfined surface. It also questions whether adhesion at the contact surface generates parallel shear stress, which would negate the concept of a free surface. Furthermore, the formation of a meniscus without adhesion is examined, emphasizing the role of surface tension.

PREREQUISITES
  • Understanding of fluid mechanics principles
  • Knowledge of surface tension and adhesion concepts
  • Familiarity with meniscus behavior in liquids
  • Basic grasp of shear stress in fluid dynamics
NEXT STEPS
  • Research the effects of surface tension on meniscus formation in different liquids
  • Explore the relationship between adhesion and shear stress in fluid dynamics
  • Study the implications of meniscus formation in capillary action
  • Investigate experimental methods to measure free surface area changes in fluids
USEFUL FOR

Students and professionals in fluid mechanics, physicists studying liquid behavior, and engineers involved in applications requiring precise fluid management.

For water in a tube wouldn't meniscus formation increase the free surface area of water
 
Physics news on Phys.org
Compared with the surface without the tube? (Note: a meniscus forms wherever a solid object is dipped into a liquid.)
Does the adhesion at the contact surface produce a parallel sheer stress? If "yes" then it is not a free surface.
Would a meniscus form at all without adhesion - i.e. from surface tension alone?
