A small bridge must be constructed across a rectangular channel. Design the possible width of the channel under the bridge (i.e., the span of the bridge) using a straight wrap transition as an inlet and outlet depending on the following data: Flow discharge (Q)= 3 m³/sec. Flow depth (y) 0.972 m. Channel width (B)= 4 m. The permissible head loss (HL)= 0.1 m. The water surface level upstream the transition (W.S.L) = 10 m. K₁ 0.2 and K2-0.4.
