Question
7. How can the dimension of a conveyance canal such as bottom width and depth
be influenced by soils in which it is built?
8. What is the theoretical velocity of a jet of water flowing out of a square orifice in
a large tank if the center of the orifice is 600 mm below the water surface?
9. Compute for the discharge in li/sec through a rectangular weir having
suppressed and contractions, if crest is 600 mm long and the water surface at
point 2.5 meters upstream from weir is 140 mm vertically above the weir crest
10. For the same length of weir crest and depth of water over the crest as in prob. 6,
compute the discharge over a trapezoidal weir. Compare with weir discharge
tables if available.
11. Show that doubling the head over a rectangular weir or trapezoidal weir makes
the discharge 2.8 times greater.
