Question
The Manning equation for a rectangular open channel is given by Q = √S(BH)/3 where is the flow rate in m³/s, S is the slope, H is the depth in m, and n is the Manning n(B+H)2/3 roughness coefficient. Determine H if Q-5, S-0.0002, B= 20 and n = 0.03. Use H-2 as starting guess Type your answer... S(BH)/3
