Energy Depth Relationship- Open Channel Flow (Chapter-3)
WebCritical flow in a channel depends on the discharge and the geometry of channel section. For a rectangular section, the critical depth is given by yc= 3 𝑄2 𝑔𝐵2 Where, yc = The critical depth, Q = The discharge and B = … Web5 de mai. de 2024 · 8. Section Factor for critical flow, Z • The section factor for critical flow computation of a channel is the product of the water area and the square root of hydraulic depth Z = A D where, Z= Section factor A = Water Area D = Hydraulic depth But remember condition of critical flow, V2/2g = D/2 Put V=Q/A and find Z = Q/ g 8. 9.
