Wet Steam Quality and Dryness Fraction

Steam - produced in a boiler where the heat is supplied to the water and where the steam is in contact with the water surface of the boiler - contains approximately 5% water by mass. Dryness fraction of Wet Steam. If the content in the steam is 5% by mass then the steam is said to be 95% dry with a dryness fraction 0.95. Dryness fraction can be expressed: = w s / (w w + w s) (1) where. = dryness fraction. w w = mass of

Effect of Water on the Surface Molecular Mobility of Poly ...

These friction force measurements and AFM observations suggest that molecular motion on the surface of the both uc- and c-PLA thin films is enhanced in the presence of water molecules. In addition in situ AFM observation of the enzymatic degradation process for the c-PLA thin film crystallized at 160 °C was carried out in buffer solution containing proteinase K at room temperature.
