What is VF and VG in steam table?
vf = Specific volume of saturated water (liquid). vg = Specific volume of saturated steam (gas).

What is the quality of saturated steam?
In thermodynamics, vapor quality is the mass fraction in a saturated mixture that is vapor; in other words, saturated vapor has a “quality” of 100%, and saturated liquid has a “quality” of 0%.
What causes saturated steam?
Saturated (dry) steam results when water is heated to the boiling point (sensible heating) and then vaporized with additional heat (latent heating).
What is the maximum temperature of saturated steam?
The steam that exists at the same temperature as the water from which it is formed is known as saturated steam. In other words, saturated steam exists at approximately 100°C (212°F) at atmospheric pressure. One of the main characteristics of saturated steam is that it is dry; i.e., it does not contain any water droplets. Another critical property of saturated steam is that it is invisible to the human eye.
What is the density of saturated steam?
Saturated vapor: wet saturated steam 15 to 35 m/s, dry saturated steam at 30 to 30 m/s. Overheated vapor: 15 to 60 m/s, according to the diameter used. For all piping (vapor, water), a minimal slope of 1 mm/m is respected, in the normal direction of flow of the fluid, in order to allow the extraction of the purging of it (vapor) and with 3 mm
How to use steam table?
Steam Table How to Use the Steam Table. In steam tables the properties of the dry steam are listed and for the wet steam the properties may be calculated from the steam tables of the dry and saturated steam. For values that are not listed exactly in the tables, the value between two figures can be obtained by linear interpolation.
What is saturated steam and superheated steam?
Superheated steam is a bad conductor of heat and has low thermal conductivity which means it will have low heat transfer co efficient. Saturated steam has better thermal conductivity due to liquid and gas particles mixture. Liquid water being a good conductor of heat, increases the overall heat transfer co efficient of saturated steam.
