What is sub cooled vapor?
Subcooled vapor refers to a vapor that is at a temperature lower than its saturation temperature at a given pressure. In other words, it is a vapor that is in a superheated state but exists at a temperature below its boiling point at the current pressure. Subcooled vapor is not in equilibrium with its liquid state and is considered to be in a superheated state.
What happens to a saturated vapor when heat is added?
When heat is added to a saturated vapor, its temperature will increase and the vapor will start to undergo phase change into a superheated vapor. This means that the vapor will contain more thermal energy than at saturation conditions, which leads to a rise in temperature without a change in pressure.
Properties of superheated vapor R134a?
Superheated vapor R134a is a phase of refrigerant R134a that exists at a temperature higher than its saturation temperature at a given pressure. It is a gas that is ready to absorb heat energy and work in a refrigeration system. Superheated vapor R134a has higher enthalpy and specific volume compared to its saturated state.
What is difference between saturated vapor and superheated vapor?
Saturated vapor is in equilibrium with its liquid phase, having reached its maximum vapor pressure at a given temperature. Superheated vapor has been heated beyond its saturation point without changing its pressure, making it hotter and less dense than saturated vapor.
What do you need for complete specifition of superheated vapour?
To fully specify superheated vapor, you need to know the substance involved (e.g., water, steam), its pressure, temperature, and specific volume. Additionally, information on the phase state (gas), the degree of superheat, and any relevant thermodynamic properties like enthalpy or entropy may also be required.
