A trapezoidal channel is carries 1 00 m3 /sec at a depth of 5 m. If the channel has a bottom width of 5 m and 1:1 side slopes, what is the flow classification (subcritical, critical, or supercritical)? What is the specific energy of flow? Also determine the total energy head if the water surface is 50 m above the energy datum. Check your solution using appropriate computer software.
