water flow speed

[mikefitz]

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?
