Saturated steam is gas-phase water that is at its condensation threshhold. That means that if the temperature is lowered or the pressure is increased, you will see condensation. An example of this would be boil-off steam in a pot: as soon as it hits the cooler surface of the pot lid, it condenses again.
This constrasts with superheated steam, which is above the saturation point due to being heated to hotter than the boiling temperature at the given pressure.
What else can I help you with?
When air is saturated it cannot hold?
… any more water vapour.
What is ill-saturated vapour pressure of a liquid?
The vapour pressure of a substance is related to how fast it is evaporating. Vapour pressure varies directly with temperature. The hotter it is, the higher the vapour pressure. A substance boils when the vapour pressure of the liquid equals atmospheric pressure pushing down on the substance: usually taken to be 760 mm Hg or 101 kPa. If you know the vapour pressure of a substance you can estimate how much of that substance would be in air above the substance if you put it in a closed room and allowed it to equilibrate. This is called the saturated vapour concentration. If you know for instance that the lower flammable limit of the substance is 0.5% (1% = 10,000 ppm), you would be concerned about the potential for fire if the saturated vapour concentration was greater than 5000 ppm at room temperature. Without ventilation, there would be enough of the substance in air to ignite if there is a source of ignition. In a similar way, if the allowable exposure limit for the substance was an 8-hour time-weighted average of 500 ppm, you would know that it is possible to be overexposed to the substance by inhalation if the saturated vapour concentration exceeds 500 ppm. Estimate the saturated vapour concentration (SVC) using the following formula: SVC = [(vapour pressure of substance in mm Hg)/ 760 mm Hg] X 10^6 Ed Gatey BSc (Chem), CRSP, CIH
What is a Binary Vapour Cycle?
A binary vapour cycle is a representation of a mercury cycle and a steam cycle on a same scale.In this vapour cycle there is comparison between the mercury cycle and steam cycle. In mercury cycle there occurs isothermal expansion of saturated water from boiler into dry saturated steam followed by isentropic expansion followed by condensation of steam and at last heating of steam and thus mercury has completed the cycle in 4 way process. In steam cycle first ther is isothermal expansion which results in converting of saturated water into dry saturated steam followed by superheated process where the steam is superheated followed by isentropic expansion of superheated steam followed by condensation of exhaust steam and at last heating of steam thus completing the cycle.
What are saturated facts?
Saturated facts are descriptive statements that are maximally saturated with content, meaning they provide all the relevant information and cannot be further analyzed or broken down. These facts are considered complete and self-contained, requiring no additional context to understand.
What is difference between saturated vapor and superheated vapor?
A metal clad heating element 8 mm in diameter and emissivity ɛ = 0.95 is horizontally submerged in a water bath. The surface temperature of the metal is maintained at 250°C under steady state conditions. Estimate the power dissipation per unit length of the heater. Assume the water is exposed to atmospheric pressure and is at a uniform temperature.
What is wet vapor?
Wet Vapour is the region which contains a mixture of liquid and vapour. The liquid is saturated liquid and the vapour is saturated vapour. The temperature stays uniform until the entire phase change is complete.
When air is saturated it cannot hold?
… any more water vapour.
When air is saturated?
when it holds all the water vapor it can hold
How do you get dew point?
Cool air at a constant pressure until it is saturated with water vapour
What is dryness fraction of steam?
it is the ratio of mass of saturated vapour to the total mass of liquid
Dry saturated steam is in a semigaseous state?
No. If you refer to the Temperature/ specific entropy (T - s) diagram for steam, the line segment to the right of the critical point (the point of zero gradient) of the curve is called the dry saturated line and the left segment is the satuated vapour line. As self-explanatory as it sounds, dry saturated steam is on the dry saturated line depending on the given temperature or pressure. The quality (dryness fraction) on the dry saturated line is by definition 1, that means there is no portion of it as vapour. Hence it is in a fully gaseous state.

Can saturated vapour pressure be used to do work?
Old steam engines used the principle of vapor pressure doing work.
Why does exhaled air saturated with water vapour?
Exhaled air is saturated with water vapor because our lungs add moisture to the air as it passes through the respiratory system. This moisture comes from the lining of the lungs and airways, as well as from water that is evaporated from the blood flowing through the lungs.
How is the fall of rain?
The sun heats up the water then the water vapour condenses into clouds. The clouds become saturated and precipitation is the result.
What is the definition of the bubble-point line?
a. The line that shows when the liquid begins to boil/evaporate b. The vapour-liquid mixture region c. Saturated vapour equilibrium line d. Saturated liquid equilibrium line e. None of the above The answer could be a), d) or e). I hope someone can clarify the accurate answer asap. Thanks.
