How to determine the minor loss for this system?

  1. Oct 6, 2008 #1
    Hi, it's me again. I've attached the diagram of the system which its minor loss is needed to be determined. Cross section profile 1 is named "cross 1" and cross section profile 2 is named "cross 2" in the given links.

    I stumbled yet another hurdle as I've never worked on two opposing flow converges at a given point. I've been through some of the books but I only encounter single direction flow only. The medium of the fluid is air by the way. Any thoughts? thanks.

    EDIT: I noticed that there is some contraction element in the junction and ultimately caused the variation in velocity between two sections. If I analyze it as though a tee branch flow, what would be the velocity that I should assumed in determining the minor head loss.

    H=K*V^2/2g
