There are many materials … WebIn the flow direction, the three labyrinth weirs are assigned the same offset, b = 20.0 cm. The trapezoidal and rectangular weirs are given the same front width as the offset, i.e., e = b = 20 cm. Each weir covers the whole flume width. The other resulting parameters are a = 34.4 cm, c = 26.9 cm, and d = 18.0 cm.
