Water flows from a large 4m detention basin (100m by 50m) alonga 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 itdrains freely to a nearby channel. Calculate the steady flow rateif: (a) the flow is assumed ideal, (b) the pipe is consideredsmooth for the purposes of the Moody Diagram. (c) the pipe has arelative roughness of 0.006. (d) the time to empty the basin forcase (c).
