h\u00a0<\/em>s<\/sub><\/em>\u00a0= entalp\u00eda de vapor “seco” (J \/ kg)<\/em><\/p>\n

h\u00a0<\/em>l<\/sub><\/em>\u00a0= entalp\u00eda de agua l\u00edquida saturada (J \/ kg)<\/em><\/p>\n

Como se puede ver, el vapor h\u00famedo siempre tendr\u00e1 una entalp\u00eda m\u00e1s baja que el vapor seco.<\/p>\n

Ejemplo:<\/strong><\/p>\n

Una etapa de alta presi\u00f3n de la turbina de vapor funciona en estado estacionario con condiciones de entrada de 6 MPa, t = 275.6 \u00b0 C, x = 1 (punto C).\u00a0El vapor sale de esta etapa de la turbina a una presi\u00f3n de 1,15 MPa, 186 \u00b0 C yx = 0,87 (punto D).\u00a0Calcule la diferencia de entalp\u00eda entre estos dos estados.<\/p>\n

La entalp\u00eda para el estado C puede seleccionarse directamente de las mesas de vapor, mientras que la entalp\u00eda para el estado D debe calcularse utilizando la calidad del vapor:<\/span><\/p>\n
