I need to calculate the minor losses in a steam header. I have calculated the major friction losses. But I can't figure out how to find the minor losses since the header has multiple tappings and not all of them will be open at the same time. How can I find the head/pressure loss introduced due to these outlets?

For context:

Main header line size : 3 inches

Tapping line size 1 inch

No of taps/outlets = 8

Length of header : 0.9m with outlets evenly spaced but alternately at 90 degrees.

(the tappings are along 2 planes which are at 90 degrees to each other. 4 along one plane and 4 along the other plane and the tappings are placed alternatively in each plane. So the distance between 2 taps which are along the same plane = 0.2m)

  • $\begingroup$ As T losses, there used to be diagrams showing types of bend or connection with an associted loss factor to include in the total head losses. Perhaps start with neutrium.net/fluid_flow/… $\endgroup$ – Solar Mike Aug 26 '19 at 6:40
