# Water flows from a large 4m detention basin (100m by 50m) along a 200mm diameter pipe for a distance of 100m at a slope... Water flows from a large 4m detention basin (100m by 50m) along a 200mm diameter pipe for a distance of 100m at a slope of 1:200. The pipe centerline is 300mm above the base of the basin and it drains freely to a nearby channel. Calculate the steady flow rate if (a) the flow is assumed ideal, (b) the pipe is considered smooth for the purposes of the Moody Diagram (c) the pipe has a relative roughness of 0.006 (d) the time to empty the basin for case (c)
