Question
Solution and answer is given, just explain the solution, and if the answer is correct.
R=0.956 m
A
R3D
P.
b=7.29- 2.828d
6.97
=0.956
b+2/2d
> Eq. (2)
Substitute b in (2) to (1):
(7.29 - 2.828d)d + d? = 6.97
7.29d - 1.828d = 6.97
1.828 d2-7.29d + 6.97 = 0
d 3D 1.59 m
d = 5.22 feet
Transcribed Image Text:R=0.956 m A R3D P. b=7.29- 2.828d 6.97 =0.956 b+2/2d > Eq. (2) Substitute b in (2) to (1): (7.29 - 2.828d)d + d? = 6.97 7.29d - 1.828d = 6.97 1.828 d2-7.29d + 6.97 = 0 d 3D 1.59 m d = 5.22 feet
Problem 8 11
A trapezoidal flume with side slope of 1:1 carries 225 ft3/s of water at a mean
velocity of 3 ft/s. The canal is laid on a slope of 0.0002 with n = 0.015.
Determine the normal depth of the canal in feet.
Solution
Q = A v
225 = A(3)
A = 75 ft2 = 6.97 m2
d.
A = bd + d2 = 6.97

v = 3 ft/s 0.915 m/s
R/3(0.0002)/2
