A rectangular channel with width 5.5 feet conveys 225 cfs. Find the normal depth if the n=0.022 and slope is 1%. (Requires “guess and check”.)  

Determine the Froude number for the channel and flow conditions in 6. State the criticality condition and describe what would have to be done to the roughness value n (increase or decrease) to result in the channel reaching the critical depth (assuming Q and s remained the same)? Explain.
