Why does the dryness fraction of steam reduce in the …

Why does the dryness fraction of steam reduce in the final stages of a steam turbine? I guess dryness fraction reduces as the steam condenses, thereby turning into liquid in the condenser. And the temperature drop is due to the heat exchanger with which the steam exchanges heat How do I estimate the dryness fraction of steam in a boiler?

2016-9-5 · Dryness Fraction of Saturated Steam (x or q) It is a measure of quality of wet steam. It is the ratio of the mass of dry steam (mg) to the mass of total wet steam (mg+mf), where mf is the mass of water vapor. X= mg mg + mf Quality of Steam It is the representation of dryness fraction in percentage: Quality of Steam = x X 100

2019-4-26 · The steam dryness fraction is used to quantify the amount of water within steam. Dry steam - all water molecules are in the gaseous state; Wet steam - a portion of the water molecules have lost their energy - latent heat - and condensed to tiny water droplets; To produce dry steam in an boiler and keep the steam dry throughout the piping system is in general not possible.

eFunda: Steam Tables: Wet Steam

In many applications, saturated steam may contain both water vapor and water droplets, so it is necessary to specify the "dryness" of the steam in order to determine its thermal properties. The dryness is the mass fraction of the vapor in a steam, so 0% dryness means all liquid with no vapor; while dryness means all steam with no liquid.
