FLUID MECHANICS - CASE STUDY

    Introduction


Capillary Action

  Peter has joined the Sandia National Laboratory as an undergraduate research assistant through a summer intership program. To let his interns better understand the property of surface tension, the laboratory director decides to demonstrate surface tension effects through capillary action. However, before starting, he asks each intern what the height will be for two different radii.

  Questions

 

Determine the height of the water column (h) for two different tube radii: R = 1 mm and 10 mm.

     
    Approach


 
  • Assume the contact angle of water with clean glass is zero.
  • Assume the water temperature is 30oC.
