Water flows at 25 m^3/s down a rectangular channel made of unfinished concrete. The channel has a width of 4 m and a downward slope of 0.008, and the water depth is 2.6 m at the control section A. Calculate critical depth, normal depth and identify the channel surface profile. Determine the distance X from A to where the depth is 2.7 m (Control Section B). Use increments of Ay= 0.1 m (one increment only between 2.6 m and 2.7 m) Take n = 0.018.

Question
Transcribed Image Text:Water flows at 25 m^3/s down a rectangular channel made of unfinished concrete. The
channel has a width of 4 m and a downward slope of 0.008, and the water depth is 2.6 m
at the control section A.
Calculate critical depth, normal depth and identify the channel surface profile.
Determine the distance X from A to where the depth is 2.7 m (Control Section B). Use
increments of Ay= 0.1 m (one increment only between 2.6 m and 2.7 m) Take n = 0.018.
