A steam coil (used for heating) has a volume of 20 L and is filled with steam at 200 kPa and 250 ° C. The inlet and outlet ports are then closed. When the coil cools down to 30 ° C (room temperature), determine: a) The reversible work of this process. b) Using an entropy balance, calculate the exergy destruction of this process. c) Using an exergy balance, calculate the exergy destruction of this process. To perform your calculations, propose values ​​for the dead state (To and Po) that are different from those of the room

A steam coil (used for heating) has a volume of 20 L and is filled with steam at 200 kPa and 250 ° C. The inlet and outlet ports are then closed. When the coil cools down to 30 ° C (room temperature), determine: a) The reversible work of this process. b) Using an entropy balance, calculate the exergy destruction of this process. c) Using an exergy balance, calculate the exergy destruction of this process. To perform your calculations, propose values ​​for the dead state (To and Po) that are different from those of the room.

Un serpentín de vapor (utilizado para la calefacción) tiene un volumen de 20 L y
se llena con vapor a 200 kPa y 250°C. Luego se cierran los puertos de entrada y
salida. Cuando el serpentín se enfría hasta 30°C (temperatura de la habitación),
determine: a) El trabajo reversible de este proceso. b) Por medio de un balance
de entropía calcule la destrucción de exergía de este proceso. c) Por medio de
un balance de exergía calcule la destrucción de exergía de este proceso. Para
realizar sus cálculos, proponga valores para el estado muerto (To y Po) que sean
distintos a los de la habitación. *
