ANTEPROYECTO DE CANAL

DISEÑAR UN CANAL RECTANGULAR REVESTIDO DE CONCRETO CON UN TRAMO TRAPECIAL DE TIERRA. INICIANDO EN EL EMBALSE LAS RANAS SABEMOS QUE EL AGUA SE ENCUENTRA ALMACENADA Y SALE DE AHI CON UN FLUJO BRUSCAMENTE VARIADO ESTO NOS VA SERVIR PARA CONOCER EL PERFIL DE ESTE CANAL.

Valores estándar de las propiedades del agua:

DE LA ECUACION DE FLUJO CRITICO DE NUMERO DE FROUD

IGUALANDO










Yc=2.267 m


-CALCULO DE LA VELOCIDAD


V=4.715 m/s

CALCULO DE AREA CRITICA
Ac=bYc
Ac=8.5(2.267)
Ac= 19.270 m2

PERIMETRO CRITICO
Pc=b + 2Yc= 8.5 + 2(2.267)
Pc= 13.034 m
RADIO CRITICO
Rc=Ac/Pc
Rc= 19.270/13.034Rc=1.478 m

GASTO
Q=VcAc
Q=4.715*19.270
Q=90.858 m3/S

-CALCULAMOS LA PENDIENTE CRITICA CON:




Sc=0.003

ScYn2 CASO 3

-ECUACION DE IMPULSO Y CANTIDAD DE MOVIMIENTO


























igualando a cero


















Y2>Yn2 POR LO TANTO LA AFIRMACION ES INCORRECTA NOS DA EL CASO 3 DONDE EL RESALTO HIDRAULICO SE FORMADESPUES DE LA PENDIENTE

-ENTONCES SUPONEMOS Y2=Yn2=3.446, Yn1=1.120 m
Yn1 > Y1 SUPOSICION CORRECTA
[pic]
1.120>1.038 SUPOSICION CORRECTA

-LONGITUD DE RESALTO
Lr= 5(Y2-Y1)
Lr= 5(3.446-1.038)
Lr= 12.040 m
