sine wave Modify Prob. 10.50 as follows. Let the water be flowing
in an unfinishedcement halffull circular channel of diameter 60 cm. Determine (a) the Froude number, (b) the
flow velocity, and (c) the critical slope.
Water flows full in an asphalt halfhexagon channel of
bottom width W. The flow rate is 12 m3/s. Estimate W if
the Froude number is exactly 0.60.
For the river flow of Prob. 10.48, find the depth y2 which
has the same specific energy as the given depth y1
12 ft. These are called conjugate depths. What is Fr2?
A clay tile Vshaped channel has an included angle of
70° and carries 8.5 m3/s. Compute (a) the critical depth,
(b) the critical velocity, and (c) the critical slope for uniform flow.
A trapezoidal channel resembles Fig. 10.7 with b 1 m
and
50°. The water depth is 2 m, and the...
