Steam for a small boiler is discharged through a pipe into a barrel containing water and after a few minutes,

Steam for a small boiler is discharged through a pipe into a barrel containing water and after a few minutes, observations were taken of the mass and temperature of the water. From the collected data given below, calculate the dryness fraction of the steam. Mass of empty barrel = 25 kg; Mass of barrel + cold water = 135 kg; Mass of barrel + cold water + steam = 140 kg; Initial temperature of water = 15 C; Final temperature of water = 42 C; Steam pressure = 8 bar; Specific heat of the material of barrel = 0.4 kJ/kg K
