Water in a Hose

  1. Apr 12, 2012 #1
    1. The problem statement, all variables and given/known data

    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?


    2. Relevant 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


    3. The attempt at a solution The problem seems simple enough, but I'm having trouble. Please help!

    Hi PhysicsCCR! :wink:

    Water is incompressible.

    Show us what you've tried, and where you're stuck, and then we'll know how to help! :smile:
