A most efficient trapezoidal section is required to give a maximum discharge of 21.5 m³/s of water. The slope of the channel bottom is 1 in 2500. Taking C-70 m2/s in Chezy's equation, determine the value of Manning's 'n' taking the value of velocity of flow as obtained for the channel by Chezy's equation.
