A rectangular channel section has a width of 2 meters and a depth of flow of 1.7 meters supports a flow of 10.2 m3/sec. The channel bed has a roughness correlating to a coefficient of 0.012. If excavation costs 650 pesos per cubic meter, compute the saving per kilometer of the canal if the most efficient trapezoidal section was instead used.
