###### Question details

A rectangular channel lined with concrete n=.013 with bottom width b=2.5m is laid on a slope of S0=.006. For this channel estimate the critical slope that will have a normal depth of flow of yc=1.5. What is the limit slope SL of this channel? Is the actual slope of the channel greater or less than the limit slope SL?
