Homework Help: Pipe Flow

  1. Jan 24, 2009 #1
    An ideal fluid flows through a pipe with radius R with flow speed v. If the pipe splits up into three separate paths, each with radius R/2, what is the flow speed through each of the paths?


    A1*v1=A2*v2



    I came up with 4v/3. Is this correct?

    Yes, your answer is correct. A good example of conservation of mass.

    Just to check... one MUST take into account all three pipes (which is what I did).
