WebbPhysical set-up at LCH Head losses are evaluated in both ow directions (from inlet A to exit B and from inlet B to exit A). For each direction, one owmeter, A or B, records the discharge owing in the set-up with an electromagnetic owmeter (Endress-Hauser PROMAG 50W). WebbIf headloss is greater than 40% of upstream pressure (as it usually is), gas compressibility can be ignored, and we can use the Darcy–Weisbach equation/ k -value method to determine headloss. The gas density used should be consistently either that upstream or downstream for headloss less than 10% of upstream pressure.

WebbThe entrance loss coefficient, Ke, is the head loss term of the energy equation for open-channel flow. The head loss coefficient is a measure of the efficiency of the inlet to smoothly transition flow from the upstream channel into the culvert. Although it is typically reported as a constant, it does vary with flow. WebbThe outlet invert level should be lower than the inlet by the amount equal to the total head loss during the, flow in the smallest pipe i.e.: 60 cm Therefore, the difference already kept is the same i.e. 60 cm.
