DISEÑO DE CANALES SECCION TRAPEZOIDAL
RESALTO HIDRAULICO
USANDO DATOS DEL TRAMO IIIDATOS:
CAUDAL(Q)= 0.32 TALUD(z)=SOLERA(b)= 0.4 RUGOSIDAD(n)=TIRANTE(y)= 0.508
resalto hidraulico para seccion trapezoidal(conociendo tirante subcritico):
ademas: r=considerando del punto B: t=
Resolviendo la ecuacion: J=
y1=
los valores que se obtienen son: PUNTO BQ = b = y2 = A = V = P = T =
FROUDE F = REGIMEN =
