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.
i dont know because im tooo dumb too answer diz question . so will u answer diz for me . post to my wall face book if u have answer it about different between saturated vapour and superheated vapour . my face book is awie yeepi .
Vapour pressure is the amount pf pressure the water in the air exerts whereas the saturated vapour pressure is upper limit of how much water can be present in the air at a given temperature
They are the same when the air is saturated and the relative humidity is 100 percent.
the saturated vapor is vapor with some percentage of moisture. on the other hand, the superheated vapor has no moisture (dry vapor).
In non-technical terms, vapor pressure is the amount of water vapor in the air and saturation vapor pressure is the amount of water vapor the air can hold at a specific temeprature.
no, when you breath out you are expelling vater vapor into the air. If the air was saturated with water vapor it could hold no more and condensation would occur.
Reeee
It is saturated.
It is saturated.
I do not now
I'm sorry, but you wrote "Difference between homogeneous and homogeneous?" If you meant the difference between homogeneous and heterogeneous, then heterogeneous nucleation is: the nucleation beginning at the surface of foreign particles. Homogeneous is: The process of creation of vapor bubble nuclei in a superheated liquid away from bounding walls and in the absence of any foreign material. Hoped that helped. :)
First of all, the term "superheated" generally refers to a vapor. This explanation refers to superheated vapor only. Superheat is the difference (in degrees of temperature) between a liquid's boiling point and the superheated vapor's actual temperature. For example; at sea level, the boiling point of water is 212ºF. As long as the temperature is 212ºF, you will have both liquid and vapor present. If you continue to add heat to the liquid/vapor mix, all the liquid will eventually become vapor. Additional heat added after no liquid remains will begin to increase the temperature above 212ºF. This resulting vapor is superheated. If you measure the temperature of water vapor to be 220ºF at 1 ATM, the vapor is superheated by 8ºF. The same analysis is true for any liquid/vapor, at any pressure and for any other temperature scale. i.e. R22 refrigerant is "saturated" (meaning both liquid and vapor are present) at 32ºF and 58PSIG. If you measure the pressure of R22 at 58PSIG but measure the temperature at 45ºF, you have measured 13 degrees of superheat. I hope this answer is useful to you. Bama Cracker Degree of superheat is the difference between the superheated temperature and the saturated temperature of the steam .
Refrigerant enters a direct expansion evaporator as a saturated liquid vapor mix and leaves as a superheated vapor.
superheated vapor is a vapor that has been heated above its boiling point.
It is saturated.
It is saturated.
It is saturated.
It is saturated.
it remains in a vapor state
becaause it was just compressed by the compressor and is the high side of the system before the tex valve
No, superheated steam gives off little energy. Most of the heat given off by steam is the latent heat of condensation as it undergoes a phase change from vapor to liquid. Superheated steam could first be "desuperheated" by adding water until it reaches the saturation point, then used for heat transfer processes.
