Homework Help: Friction losses due to expansion vs losses due to contract

  1. Apr 9, 2016 #1
    1. The problem statement, all variables and given/known data
    i was told that the losses during expansion are usually much higher than losses during contraction in pipe . is it true?why?

    2. Relevant equations


    3. The attempt at a solution

    Friction of what on what?

    Edit: having seen your next thread, I realise the pipe is not expanding or contracting. It only seems that way to a flow passing along it. (I thought this was about thermal expansion, or expansion under stress.)
    And by friction, do you mean viscosity? Turbulence?
