Question 122

Does air create a friction force on water? Would a gutter be much quicker at having water flow through it, rather than a pipe?
Air does exert frictional forces on water, but much less than a surface would. Thus a gutter would be a better water carrier than a pipe. It would have one less surface to slow the flow of water.
