Solve it with correct answer
Transcribed Image Text:The specific energy, E, is defined as the total energy head with respect to the channel or pipe bottom. In
this case, z = 0 and P =d (flow depth). Therefore,
E-d+ v'/28
(equation 1)
A rectangular channel of width w - 5 m carries a flow of Q- 1 m'/s.
• Find the specific energy corresponding to a flow depth of d = 20 cm.
(a) E= 0.15 m (b) E 0.20 m (c) E = 0.215 m (d) E = 0.25 m (e) E - 0.30 m
(f) None of the above, but the answer is: E=
