What is a triple point line in thermodynamics?
It is the state at which all the three phases i.e.,solid phase,liquid phase and vapor phase are in equilibrium.
What is suction and discharge superheat?
Suction superheat is the heat added to the refrigerant above that required to change its state from liquid to vapour (as happens in the evaporator). This heat is added both in the evaporator, in the suction line and (where applicable) in the suction accumulator.Discharge superheat is suction superheat plus heat of compression, and must be removed in the condenser before condensation, the change of state from vapour to liquid, can occur.The HVAC Veteran
What is flooding in distillation column?
As the reflux minimizes and heat energy remains to same that time sudden increase in pressure drop takes place. As the vapour flow is higher compared to liquid flow so liquid is unable to comes down through downcomer and flooding occurs......
What is steam in thermodynamics?
Saturated steam is gas-phase water in equilibrium with liquid water at the same temperature and pressure. If the temperature is above the saturation point and/or the pressure is below the saturation pressure, the steam is "superheated steam". In either case it is a gas. There are some conventions where saturated steam along with some fraction of liquid water in equilibrium with it is still referred to as steam even if not all of it is gas, as long as at least some of it is gas.
What is crude oil true vapor pressure?
True Vapor Pressure is the pressure of the vapor in equilibrium with the liquid at 100 F (it is equal to the bubble point pressure at 100 F)
What is equilibrium vapor pressure?
It is vapor molecules in equilibrium with a liquid in a closed system exert a pressure proportional to the concentration of molecules in the vapor state.
What is dynamic equilibrium Describe what is happening to the liquid and vapor at the boundary of a liquid that is in dynamic equilibrium Is the overall balance of liquid and vapor changing?
1. Dynamic equilibrium is when the rate of vapour and liquid being produced has stabilized, and stopped changing. It's called dynamic equilibrium because the liquid hasn't stopped changing into vapour, and the vapour hasn't stopped changing into liquid, but the rates of these two changes has stabilized so that there is a constant amount of liquid and vapour present.2. At the boundary of the liquid, particles with sufficient energy break away from the liquid and become vapours, and vapour molecules with low energy, or those that make contact with the surface of the liquid, become bonded to the liquid. There is a constant exchange of particles, hence dynamicequilibrium3. No, the overall balance of liquid is constant, hence equilibrium.
Can be a liquid or gas?
Substance at Vapour - Liquid phase equilibrium can exist as both liquid or gas at the same time.
What factors affect the vapour pressure of a liquid?
Vapor pressure or equilibrium vapor pressure are the pressure of a vapor in thermodynamic equilibrium with its condensed phases in a closed bottle. All liquids and solids have a tendency to evaporate into a gaseous form, and all gases have a tendency to condense back to their liquid or solid form.The equilibrium vapour pressure is an indication of a liquid's evaporation rate. It relates to the tendency of particles to escape from the liquid (or a solid). A substance with a high vapour pressure at normal temperatures is often referred to as volatile
What kind of pressure of a liquid is the pressure exerted at equilibrium and is dependent on temperature only?
Vapour pressure ; yes
Process in which vapour molecules are recaptured by molecules at liquid surface?
I suppose that dynamic equilibrium is the adequqte term.
Vapor pressure results from?
pressure of gas over its liquid equilibrium
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.

What is kinetic vapour pressure?
Kinetic vapor pressure which is defined as the pressure exerted when a solid or liquid is at equilibrium with its own vapor.
Why is 0 degree Celsius called as triple point?
In triple point,all phases of water, vapour,Liquid water and ice is @ equilibrium.
