General equation of velocity along the pipe

  1. Jun 17, 2016 #1
    1. The problem statement, all variables and given/known data
    A pipe diameter changes from 0.5m to 1m in a length of 1m in a pipe diffuser . If a discharge Q flows from 0.5m diameter towards 1m diamater , obtain the general expression for velocity at the pipe cross section .

    2. Relevant equations


    3. The attempt at a solution
    since we know that the velocity of fluid in pipe decreases when the size of pipe increases , So , my working is Velocity at the entrance - (difference in velocity between entrance and exit / area of pipe ) , where the area of pipe has the diameter which increases from the entrance ) , i let is as x in my working . Is my working correct ?

    You can simply use equation of continuity.
    Check if your equation is dimensionally correct.

    I just see a diagram. If there is any working associated with it, it is not visible.
