Head Required for Open Channel
Head Required for Open Channel
(OP)
How would you calculate what is the head required to drive flow at 6 ft/s thru an open rectangular channel (5 ft wide and 15 ft deep), that has zero slope and that is approximately 90 ft in length?

If I were to use manning's equation, would I have to solve for R? That doesn't seem to give an answer for what type of head is needed on the upstream end to maintain a velocity of 6 ft/s in the downstream concrete channel.
