At 645.3 kPa and 151.2°C, steam leaves an industrial boiler. When the calorimeter pressure reaches 104.3 kPa, a part of the steam is fed through a throttling calorimeter and expelled to the atmosphere. If the steam temperature at the calorimeter is 113.8°C, a. how much moisture is exiting the boiler container? b. If the mass of the saturated liquid is 15 kg, calculate the mass of the saturated vapor. @ 645.3 kPa and 151.2°C: hf = 624.56 kJ/kg hfg = 2123.3 kJ/kg @ 104.3 kPa and 113.8°C: h2 = 2506.7 kJ/kg
