A 15-inch sanitary sewer (n=0.01) was placed at a slope of 0.005. Under the peak flow condition, water depth in this pipe was measured as 9.75 inches. (1) What is the peak flow rate? (2) If the peak flow rate is 3 times of the average flow, what will be the water depth and flow velocity in the pipe under the average flow condition?
