=Homework Problem: Longest Vertical Soda Straw

In summary, the person is seeking guidance on how to approach a homework problem about the longest vertical soda straw one could possibly drink from. They are unsure of where to start and are looking for a small push in the right direction. The question may involve cohesive and adhesive forces and the force exerted by sipping through a straw. The other person mentions thinking about atmospheric pressure when sucking through a straw and reminds the person not to repeat their questions as they have already received a good answer earlier.

I received a homework problem that I need guidance on where to start.

What is the longest vertical soda straw you could possibly drink from?

I do not know where to start on this problem. A small push in the right direction would be greatly appreciated.

Can you please specify your doubt a bit more. I didn't understand what the question means?
 
  • #3
Probably something to do with cohesive and adhesive forces? or over coming gravity by the force exerted by the sipping the straw
 
  • #4
Think about what's actually happening when you suck.

You're not so much pulling liquid up the tube as much as allowing atmospheric pressure to push it up.

Oh, and please don't repeat your questions. I've just seen that you had a good answer given just a few hours ago, the first time you asked.
