Homework Help: Find the speed of flow in the second pipe of an ideal fluid

  1. Nov 11, 2009 #1
    1. The problem statement, all variables and given/known data
    An ideal fluid with the density of 0.85 x 103 flows at 7.0 m/s through a level pipe with a radius of 0.50 cm. The pressure in the fluid is 1.4 x 105 N/m3. This pipe connects to a second level pipe with radius of 1.5 cm. Find the speed of flow in the second pipe

    2. Relevant equations
    Bernoulli's Equation
    P1+ 1/2density(g)(y1) + density(g)(y1) = P2+ 1/2density(g)(y2) + density(g)(y2)
    P + 1/2(density)(v) + density(g)(y)

    3. The attempt at a solution
    Unsure how to find pressure and velocity.

    First of all, you have to get the equation right. Wtih Bernouilli's equation stated correctly you will see the solution.
