EXERCICIO 1
Q = 118 mᶾ/s
Lamina d’agua = 2,5m
Largura = 22m
Q = VA →V=Q/A
V = 118/2,5.22 = 2,15m/s
Fr=Vmgh=2,159,81.2,5=0,43<1=Regime Fluvial
ALTERNATIVA B
EXERCICIO 2
V = 1,23m/s
A = (29,375+20,75)/2.3,45=86,4656m²
Q = 86,46x1,23 = 106,35mᶾ/s
ALTERNATIVA E
EXERCICIO 3
Vc=g.Yc=9,8.0,58
Vc = 2,384 m/s
Fr=Vmgh=2,392,39=1,00=Regime Critico
ALTERNATIVA D
EXERCICIO 4
L₁ = 4,202+4,202=5,94m
L₂ = 6,20m
L₃ = 4,202+4,202=5,94m
P = 5,94+6,20+5,94 = 18,08m
A = (14,60+6,20)/2.4,20=43,68m²
Rh = A/P = 43,68/18,08 = 2,42m
ALTERNATIVA C
EXERCICIO 5
Declividade = 678,90-673,45 = 5,45m
Sf = I = ΔΗ/L = 5,45/3960 = 0,0014m/m n = 0,026
Rh = 2,42m
A = 43,68m²
Qmax = A/n.Rh⅔.I½
Qmax = 43,68/0,026.2,42⅔.0,0014½
Qmax = 113,30mᶾ/s
ALTERNATIVA E
EXERCICIO 6
Seção Retangular
A = 14,60 x 4,00
A = 58,40m²
P = 14,60 + 2 x 4,00
P = 22,60m
Rh = 58,40/22,60 = 2,58m
Qmax = A/n.Rh⅔.I½
Qmax = 58,40/0,018 x 2,58⅔ x 0,0014½
Qmax = 228,36m³/s
ALTERNATIVA D

EXERCICIO 7
Seção 1 h1 = 43cm = 0,43m
V1 = 12,8 m/s
L = 12m
Q = V x A
Q = V1 x 3 x L x h1
Q = 12,8 x 3 x 12 x 0,43
Q = 198,14m³/s
Fr=Vmgh=12,89,81.0,43=6,24 >1=Regime Torrencial
ALTERNATIVA C
EXERCICIO 8 q = Q/L = 198,14/3x12,00 = 5,50m³/s.m h2 = - h1/2 + √2q²/g.h1 + h1²/4 h2 = - 0,43/2 + √2.5,5²/9,8.0,43 + 0,43²/4 h2 = 3,58m
Q = V.A -> V=Q/A
V₂ = 198,14/3.12.3,58
V₂ = 1,54m/s
Fr = 1,54/√9,8.3,58 = 0,26
