Q! A radiator of steam heating system has a volume of 0.2 m'. When the radiator is filled with saturated steam at a pressure of 1.5 bar all valves are closed. After a period of time the pressure inside the radiator becomes 1.4 bar due to heat lost to surrounding air. Calculate: 1- mass of steam within the radiator. 2- mass and volume of liquid water at the final state. 3- mass and volume of vapor at the final state. From steam tables, at 1.5 bar,

Question
Q/ A radiator of steam heating system has a volume of 0.2 m'. When the radiator is filled with saturated steam at a pressure of 1.5 bar all valves are closed. After a period of time the pressure inside the radiator becomes 1.4 bar due to heat lost to surrounding air. Calculate: 1- mass of steam within the radiator. 2- mass and volume of liquid water at the final state. 3- mass and volume of vapor at the final state. From steam tables, at 1.5 bar, Since all valves are closed the specific volume of steam remains constant as heat is lost. At 1.4 bar, Since v2 < v g at 1.4 bar the steam becomes wet.
