Homework Help: Fluid velocities

  1. May 14, 2009 #1
    1. The problem statement, all variables and given/known data

    A pipe of 150mm bore is delivering water at a rate of 7500 liter/min at a pressure of 820 kPa. It connects via a horizontal, gradually expanding pipe, to a main of 300mm diameter. calculate the fluid velocities both in the main body of the pipe and at the outlet.

    2. Relevant equations

    m= p1A1v1 = p2A2V2

    3. The attempt at a solution

    Is the equation above correct to use for this problem. Thanks in advance.

    Yup, if all you're concerned about is flow rate, then continuity is all you need assuming you have areas...which you do!
