The dryness fraction of steam
WebDryness fraction (x) = Mass of vapour / Mass of the sample. Dryness fraction (x) = MV/ (MV+ ML) Where, MV - Mass of vapour. ML - Mass of liquid. Value of dryness fraction (x) will vary between zero and one. If value of dryness fraction (x) is 0, it indicates that working fluid is at saturated liquid state and if value of dryness fraction (x) is ... WebEngineering Mechanical Engineering Combined separating and throttling calorimeter is used to find out dryness fraction of steam, following readings were taken: Main pressure = 12 bar abs. Mass of water collected in separating calorimeter = 2 kg.
