Water flow speed

  1. Nov 2, 2006 #1
    Water entering a house flows with a speed of 0.22 m/s through a pipe of 2.3 cm inside diameter. What is the speed of the water at a point where the pipe tapers to a diameter of 5 mm in m/s?

    Area 1 = 4.155
    Area 2 = 19.635

    Flow 1 = 4.155 (.22) = .914 m/s
    .914 = 19.635v
    v=.04655 mm/s

    convert .04655 mm/s to m/s = 465500m/s - woah, wrong! any ideas?
