a. A trapezoidal channel has a bed slope of 3m in 5km and a Mannings Coefficient of n = 0.013.Calculate: The area, A The wetted perimeter, P hydraulic radius, R The velocity, The Volumetric Flow rate. a. Use the Manning's equation to calculate the slope S for the following channel shape andvariables: W = 4.1 m, y = 3, x*y = 1 m A = (W+xy)y p= W + 2yv1+x² U = 3.2 m/s N = 0.016 R = A/P
