Read the question carefully and give me both a&b right solutions. A 1.3-m wide rectangular channel with a bed slope of 0.00019 has a depth of flow of 0.8m. Manning’s roughness coefficient is 0.017. (a) Can Manning’s equation be applied to this system (i.e., is the flow fully turbulent)? (b) Regardless of the answer to part a, determine the steady uniform discharge in the channel.
Uniform flow occasionally occurs in a 5-m-diameter circular concrete conduit but the depth of flow can vary. The Manning's coeffic ient is n= 0.013, and the channel slope is 0.0005. (a) Calculate the discharge for y = 3 m, (b) Plot the discharge-depth curve.
