Question

5.)When dry saturated steam is further heated, its dryness fraction.​

Answer 1

Answer:

As the water/vapour mixture increases in dryness, its condition moves from the saturated liquid line to the saturated vapour line. Therefore at a point exactly halfway between these two states, the dryness fraction (c) is 0.5. Similarly, on the saturated steam line, the steam is 100% dry.

Answer 2

Answer:

• When water is heated to the boiling point and then evaporated with further heat, saturated steam is produced. When this steam is heated above its saturation point, it is known as superheated steam.

• Steam is considered to be 90% dry, or have a dryness fraction of 0.9, if it contains 10% water by mass.

• As the dryness of the water/vapour mixture rises, its condition shifts from saturated liquid to saturated vapour. As a result, the dryness fraction (c) is 0.5 at a position exactly midway between these two states.
