Hoja1Un canal trapezoidal con b=20 pies, z=2, S0=0.0016 y n=0.025 conduce un caudal de 400pies3/s. Calcule el perfil de remanso creado por una presa que embalsa el agua hasta una profundidad de 5 pies inmediatamente detrs de la presa. Se supone que el extremo de aguas arriba del perfil es igual a una pronfundidad 1% mayor que la profundidad normal. El coeficiente de energa es 1.10.Q400n0.025So0.0016yc2.221.1b20z2Zc74Kn10000yTARR2/3KZdx/dyAx5.0040.00150.003.542.32320,769290.57614.8039.20142.083.432.27319,246270.57921551554.6038.40134.323.312.22117,783251.28351633184.4037.60126.723.192.16916,379232.68961734914.2036.80119.283.082.11515,035214.79881886794.0036.00112.002.962.06013,749197.51,1412138923.8035.20104.882.842.00312,521181.01,4372581,1503.6034.4097.922.711.94511,351165.22,2323671,5173.5534.2096.212.681.93011,067161.42,6891231,6403.5034.0094.502.651.91510,787157.53,4641541,7943.4733.8893.482.631.90610,621155.34,2571161,9103.4433.7692.472.611.89710,456153.05,6161482,0583.4233.6891.792.601.89110,346151.57,2301282,1863.4033.6091.122.591.88510,238150.110,3111752,3623.3633.4489.782.561.87310,022147.1Resuelva el ejemplo 10-1 suponiendo que alfa = 1.0 y examine el efecto del valor de alfa en la forma del perfil de flujo.
