Para calcular a altura da lâmina de água de uma galeria de drenagem urbana de seção circular, construída em concreto (n = 0,013), com diâmetro de 700 mm e declividade de fundo de 0,4 %, transportando uma vazão de 500 L/s, podemos utilizar a equação de Manning-Strickler: Q = (1/n) * A * R^(2/3) * S^(1/2) Onde: Q = vazão (m³/s) n = coeficiente de rugosidade de Manning A = área da seção transversal (m²) R = raio hidráulico (m) S = declividade da linha d'água (m/m) Para encontrar a altura da lâmina de água, podemos utilizar a equação da área da seção transversal: A = (π * D²) / 4 Onde: D = diâmetro (m) Substituindo os valores na equação de Manning-Strickler, temos: 500/1000 = (1/0,013) * [(π * 0,7²) / 4] * R^(2/3) * (0,004/100)^(1/2) R^(2/3) = (500/1000) * (0,013/π) * 4 / [(π * 0,7²) * (0,004/100)^(1/2)] R^(2/3) =
