Exemplo: C\u00e1lculo do Trocador de Calor<\/h2>\n

\"exemplo<\/a>Considere um\u00a0trocador de calor de fluxo paralelo<\/strong>\u00a0, usado para resfriar o \u00f3leo de 70 \u00b0 C a 40 \u00b0 C usando \u00e1gua dispon\u00edvel a 30 \u00b0 C.\u00a0A temperatura de sa\u00edda da \u00e1gua \u00e9 de 36 \u00b0 C.\u00a0A taxa de fluxo de \u00f3leo \u00e9 de 1 kg \/ s.\u00a0O calor espec\u00edfico do \u00f3leo \u00e9 de 2,2 kJ \/ kg K.

    A diferen\u00e7a logar\u00edtmica de temperatura m\u00e9dia pode ser calculada simplesmente usando sua defini\u00e7\u00e3o:<\/p>\n

    1. \u00c1rea do trocador de calor<\/li>\n<\/ol>\n

      Para calcular a \u00e1rea desse trocador de calor, precisamos calcular a taxa de fluxo de calor usando a taxa de fluxo de massa de \u00f3leo e LMTD.<\/p>\n

      \"Balan\u00e7o<\/a><\/p>\n

      A \u00e1rea requerida deste trocador de calor pode ser calculada diretamente usando a equa\u00e7\u00e3o geral de transfer\u00eancia de calor:<\/p>\n
