An irrigation canal with trapezoidal cross-section has the following elements. Bottom width = 2.1 m depth of 1.0 m, side slope of 1.5 horizontal to 1 vertical, slope of canal bed = 0.0001, coefficient of roughness = 0.02. The canal will serve clay-loam rice land. 40. What is the hydraulic radius in meters? 41. What is the mean velocity of the flow in m/s 42. If the canal will serve a clay-loam rice land, determine the area in hectares it can serve if the duty of the water per hectare is 1.355 L/s
