Q8. The flow rate Q of rectangular cross section channel is determined by the following equation: = 1/ (B SE yB yB nB + 2y Where, Q is the flow rate. B is the width of the channel. Q S is the channel slop. Write MATLAB Script to perform the following tasks: 1. Determine the width B that will give a flow rate of Q = 13.5m/s. Assume that y = 5.2m, S = 0.0015 and n= 0.017. find the result with 1 increment. 2. Plot the results of B vs Q use proper labels for x and y axis.
