1. Se tiene un mezclador con tres alimentos donde todas las propiedades son especificadas en la tabla que se presenta. Se quiere obtener una fracción molar de ethanol a la salida del mezclador de 0.5. Para cumplir esta especificación, en cuanto se debe incrementar el flujo de la corriente 2?. Halle la respuesta haciendo un análisis de sensibilidad y usando la herramienta design specification ofrecida por ASPEN.
