Homework Help: Pipe bend fluid mechanics problem

  1. Oct 27, 2011 #1
    1. The problem statement, all variables and given/known data

    The pipe shown has a 180° horizontal bend in it as shown, and D is 20 cm. The
    discharge of water (ρ = 1000 kg/m3)in the pipe and bend is 0.30 m3/s, and the
    pressure in the pipe and bend is 100 kPa gage. If the bend volume is 0.10 m3 and
    the bend itself weighs 500 N, what force must be applied at the flanges to hold the
    bend in place?


    Thanks alot in advance, having problems with this question on a project, havent seen one like it

    2. Relevant equations

    perhaps momentum equation?

    3. The attempt at a solution

    "perhaps momentum equation?"

    That is correct. Apply it and let's see your work.
