In a piping system, what added resistance is in a 45 degree y-piece that isn't in a 45 degree bend? Why is the pressure drop over a y-piece greater?

    In a wye you are splitting or adding the flow from one pipe to two pipes. This causes more turbulence. If you are splitting the flow the flow hits the vertex of the wye making an area of zero flow. etc.
