Pressure in a pipe of varying size

  1. Mar 21, 2010 #1
    1. The problem statement, all variables and given/known data

    Use the picture as a guide. P is the pressure in the pipe, and vi is the speed of a non-viscous incompressible fluid at locations i = 1,2,3,4,5.(For each statement select correctly)


    Options are: Greater than, less than and Equal to
    v1 is .... 2v3.
    P1 is .... P2.
    P1 is .... P4.
    P3 is .... P4.
    v4 is .... v5.
    v1 is .... v2.
    P4 is .... P5.

    2. Relevant equations

    Bernoulli's: P+1/2pv^2+pgh=Constant

    3. The attempt at a solution

    -Equal to
    -Greater than
    -Greater than
    -Less than
    -Greater than
    -Greater than
    -Greater than

    This is my most recent attempt. I have 20 attempts and have used 5, but I still don't see where I am going wrong here. The assignment is due at midnight and this is my last question (current time is 10:15PM), so this is my last option.
