15. A circular pipe has a diameter of 1 m, bed slope of 1 in 1000, and Manning's roughness coefficient equal to 0.01. It may be treated as an open channel flow, when it is flowing just full, i.e. the water level just touches the crest. The discharge in this condition is denoted by Qull. Similarly, the discharge when the pipe is flowing half, i.e. with a flow depth of 0.5 m, is Qfull denoted by Qhalf. The ratio is Qhalf
