Aula 14 Prof. MSc. Luiz Eduardo Miranda J. Rodrigues Exercício 1 1) Deseja-se elevar água do reservatório A para o reservatório B. Sabe-se que a vazão é igual a 4 litros/s, determine: a) A velocidade da água na tubulação de sucção. b) A velocidade da água na tubulação de recalque. c) A potência da bomba. d) O tempo necessário para se encher o reservatório B. Dados: γ H2O = 10000N/m³, g = 10m/s², d suc = 10cm, d rec = 5cm, V B = 10m³, η B = 70%. (3) 20 m sucção (2) B recalque B M ref 2m (1) A aberto com nível constante Mecânica dos Fluidos
Aula 14 Prof. MSc. Luiz Eduardo Miranda J. Rodrigues Solução do Exercício 1 a) Velocidade na sucção: b) Velocidade no recalque: Q V v = v v suc suc suc = v ⋅ A Q A V suc QV = 2 π ⋅ d suc 4 4 ⋅ QV 4 ⋅ 4 ⋅10 = 2 v suc = π 2 ⋅ d π ⋅ 0,1 suc −3 Q V v = v v rec rec rec = v ⋅ A Q A V rec QV = π ⋅ d rec 4 4⋅QV = 2 π ⋅d rec 2 v suc = 0,51m/s v rec = 4 ⋅ 4 ⋅10 π ⋅ 0,05 −3 2 v rec = 2,03 m/s Mecânica dos Fluidos
