Diagrama de Moody<\/h2>\n

O diagrama de Moody (tamb\u00e9m conhecido como gr\u00e1fico Moody) \u00e9 um gr\u00e1fico na forma n\u00e3o dimensional que relaciona o fator de atrito de Darcy<\/strong><\/a>\u00a0, o\u00a0n\u00famero de Reynolds<\/strong><\/a>\u00a0e a\u00a0rugosidade relativa do<\/strong><\/a>\u00a0fluxo totalmente desenvolvido em um tubo circular.<\/p>\n

Exemplo: Diagrama Moody<\/h2>\n

Determine o fator de atrito<\/strong>\u00a0(f\u00a0D<\/sub>\u00a0) para o fluxo de fluido em um tubo de 700 mm de di\u00e2metro com o n\u00famero de Reynolds de 50 000 000 e uma\u00a0rugosidade absoluta<\/strong>\u00a0de 0,035 mm.<\/p>\n

Solu\u00e7\u00e3o:<\/strong><\/p>\n

A rugosidade relativa \u00e9 igual a \u03b5 = 0,035 \/ 700 = 5 x 10\u00a0-5<\/sup>\u00a0.\u00a0Usando o Moody Chart, um n\u00famero de Reynolds de 50 000 000 cruza a curva correspondente a uma rugosidade relativa de 5 x 10\u00a0-5<\/sup>\u00a0a um fator de atrito de\u00a00,011<\/strong>\u00a0.<\/p>\n

Fator de atrito de Darcy para v\u00e1rios regimes de fluxo<\/h2>\n

A classifica\u00e7\u00e3o mais comum dos\u00a0regimes<\/a>\u00a0de\u00a0fluxo<\/a>\u00a0\u00e9 de acordo com o n\u00famero de Reynolds.\u00a0O n\u00famero de Reynolds<\/strong>\u00a0\u00e9 um n\u00famero adimensional composto pelas caracter\u00edsticas f\u00edsicas do fluxo e determina se o fluxo \u00e9\u00a0laminar ou turbulento<\/strong>\u00a0.\u00a0Um n\u00famero crescente de Reynolds indica uma crescente turbul\u00eancia do fluxo.\u00a0Como pode ser visto no gr\u00e1fico Moody, tamb\u00e9m o fator de atrito de Darcy \u00e9 altamente dependente do regime de fluxo (ou seja, do n\u00famero de Reynolds).<\/p>\n
