###### Question details

A triangular open channel is constructed of smooth concrete (n=0.013). The channel is the shape of an upside-down equilateral triangle with a width at the top of 2 m. The channel is full. Water flows at 3m3 /s in uniform flow. Determine the following: a. The hydraulic radius of the channel b. The minimum slope c. Given the minimum slope, what would the flow rate be if the fluid depth is reduced 50%?
