Water
200 kPa
300°C
The tank contains 2kg of water at 20C, 1 atm. The tank is heated. When the tank pressure reaches 300kpa, the valve opens and steam starts escaping. Heating continues and steam continues to escape while the pressure remains constant until half of the mass escapes. At this time the tank is filled with saturated vapor at 300 kpa, and the valve closes.
Question: Determine the volume of the tank and the amount of supplied heat.
