A rectangular concrete channel (n=0.015, S_o = 0.005) has a bottom width of 6.0 m and a discharge rate of 25 m^3/s.
1) Compute the normal depth y_n
2) Compute the critical depth y_c
3) Compute the minimum specific energy E_min
4) Determine the channel slope that would result in critical flow
5) The specific energy for a water depth of 1.9 m
6) The water depth for the specific energy of 2.2 m
7) Plot the specific energy diagram for depths ranging from 0.5 to 2.0 m
