Units: ft=foot, m=meter, s=second.
Minor Loss Equation:
g = acceleration due to gravity = 32.174 ft/s2 = 9.806 m/s2.
hm = head loss due to a fitting and has units of ft or m of fluid. It is the energy loss due to a fitting per unit weight of fluid.
K = minor loss coefficient for valves, bends, tees, and other fittings - table of minor loss coefficients.
The minor loss calculation is valid for open channels (including partially full culverts) as well as closed conduits (circular or non-circular) flowing full. The minor loss calculation does not check for unreasonable inputs such as negative values. All values should be entered as positive.
