Question

1kg of wet steam contains 0.8 kg of dry steam, then dryness fraction (x) is?​

Answer 1

Given:

Mass of wet steam = 1 kg

Mass of dry steam = 0.8 kg

To find:

Dryness fraction (x)

Solution:

Dryness fraction is the amount of water within steam. Wet steam consists of dry saturated steam and water particles suspended in it. the dryness ratio is defined as the ratio of mass of dry saturated steam to the total mass of wet steam.

Dryness fraction x = Mass of dry steam/ Total mass of wet steam

x = 0.8/1

x = 4/5

Therefore, the dryness fraction is 4/5.
