En un dispositivo cilindro-émbolo, se tiene agua inicialmente como vapor saturado a 1,5 bar. Se extrae 490 kJ/kg de calor a presión constante hasta que su volumen específico llega a 0,907 m3/kg. Posteriormente, se le suministra calor a volumen constante hasta que la presión alcanza los 3 bar. Suponiendo que es posible despreciar variaciones de energía mecánica: a. Escriba el balance energético para este sistema cerrado.
b. Identifique las propiedades termodinámicas v y u para cada uno de los tres estados.
c. Calcule el trabajo, calor y variación de energía interna (por unidad de masa) para los procesos 1-2, 2-3.
