2.15 Manning's equation can be used to compute the velocity of water in a rectangular open channel: U=VS(BH) ВН B₁+ 2H n n where U = velocity (m/s), S = channel slope, n = roughness coeffi- cient, B = channel width (m), and H = water depth (m). The follow- ing data are available for five channels: 0.035 0.020 0.015 0.030 0.022 2/3 matrix S 0.0001 0.0002 0.0010 0.0007 0.0003 B 682450 10 15 H 2.0 1.0 1.5 3.0 2.5 Create Python statements to store these values in a matrix P where each row represents one of the channels and each column represents one of the parameters. Add one or more statements to compute the velocities in a column vector U based on the values in the parameter
