Q6) An open channel of constant dimensions has a rectangular cross-section area. Under uniform flow conditions, the water flow is calculated using the following equation. YnB YnB Q n n [B + 2ym B 2/3 51/2 where Q is the flow rate, y, is normal depth, B is the width of the channel, n is the roughness coefficient and S is the channel slope. 1. Write a MATLAB function that represent the equation. 2. Write a MATLAB script to determine yn, when Q=14.15m/s, B=4,572m, n=0.017 and S=0.0015. Use the function that you created. 3. Fill the blank with the final answer of part 2_4= 4. Create a figure that contain tow sub plot the first for Q vs S using S ranges from 0.0001 to 0.001 and the second for Q vs B using B ranging from 3 to 4
