Homework Help: Water Pressure in a Pipe

  1. Nov 11, 2008 #1
    1. The problem statement, all variables and given/known data
    Water flows at 6.1 m/s in a horizontal pipe with a pressure of 3 ´ 104 N/m2. If the pipe widens to twice its original radius, what is the pressure in the wider section? Give answer in Pascals.

    2. Relevant equations
    volume = length x area
    rate = volume / time
    rate = volume x area

    3. The attempt at a solution

    Again, my professor's equations leave a bit to be desired. If anyone has a better equation (or is willing to help me solve this problem) please let me know. Sorry to post twice in a row!

    Since the question is asking for Pressure, try to find an equation that includes Pressure. Also, give this a thought, would the pressure increase or decrease if the area increases?
