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
