Determine os os estados termodinâmicos da água, nas questões de b a q abaixo, são de líquido comprimido, mistura líquido-vapor, vapor superaquecido ou se estão nas linhas de líquido saturado ou vapor saturado. Determine também os valores das propriedades: Volume específico (v), energia interna (u), entalpia (h), e entropia (s), para cada estado, e o valor do título quando tratar-se de uma mistura. Utilize as tabelas de propriedades termodinâmicas para a água 2.4.1, 2.4.2, 2.4.3 e 2.4.4. b) p = 25 Bar; T = 180°C; Estado termodinâmico -
