QUESTIONS AND ANSWERS
 
Question 111

In the book section on Water Distribution, there was a question (exercise 5) about a novelty straw. The answer says that the straw can't be taller than 0.5 meters. I thought you could suck liquid up a straw 10 meters tall? Why can this straw only be 0.5 meters tall?
The question itself said that the straw was only 0.5 meters tall. In the answer I was intending to point out that you can have as much tubing as you like in that straw, because it's only 0.5 meters tall overall. I didn't intend to mean that straws taller than 0.5 meters but shorter than 10 meters wouldn't work. Just that a short straw will work no matter how much tubing it contains. Sorry for an imperfect answer in the book. I'll change it in future editions.
