    Square ducting

    How much do junction loss constants in square pipes differ from loss constants for circular pipes? For example, a circular cross section pipe with a 90 degree elbow may have a loss coefficient of 0.2. How much would this value differ from the loss coefficient for a 90 degree elbow in square...

    Pipe end and branch

    I have a pipe which is closed at one end and has a branch coming off it near the closed end. Can I treat this as a simple 90degree bend or would the 'dead end' cause noticable resistance to the flow? Would there be resistance coefficients for this case in ASHRAE Fundamental publications?
