Solving Water Flow in a Taper Pipe Problem

[PhysicsCCR]

Homework Statement

Water entering a house flows with a speed of 0.228 m/s through a pipe of 1.08 cm inside radius. What is the speed of the water at a point where the pipe tapers to a radius of 2.39 mm?

Homework Equations

Continuity equation: A1V1 = A2V2

Bernoulli's Principle: P1 + .5pv1^2 + pgh1 = P2 + .5pv2^2 + pgh2, where P = Pressure,
p = density.

Volume of a cylinder = pi (r)^2 (h)

Area of a cylinder = 2pi (r)^2 + 2pi (r)h

The Attempt at a Solution

The problem seems simple enough, but I'm having trouble. Please help!
