when pressure on the suction side of the pump drop below the vapour pressure of the liquid, vapour forms. It's caused because of insufficient suction head, high suction lift, excessive friction head, or high liquid temperature.
Water Vapour
Binding machines have made the jobs and lives of those in the publishing industry vastly easier. They work by taking submitted manuscripts and sealing the pages together with a sealant and hardcover or paperback binding.
in orde to reduce the pressure........cming from the evaporator
Wire binding machines are commonly found in professional office settings. The machines punch holes in stacks of paper, and then binds the paper together using wire. They are used to quickly and easily bind presentations in a professional manner.
If the pressure of a wet vapour is ≤ 2000 kPa and the dryness fraction is ≥ 0.9, then (if you wish) you may use: Vx=XVg ; where Vx is the specific volume you are solving for, X is dryness fraction and Vg is the specific volume of the saturated vapour at the given state (pressure, temp, etc).Otherwise use: Vx = (1 - X)Vf + XVg ; and in this case Vf being the specific volume of the saturated liquid at the given state.The specific volume of wet steam is quite simply, the volume per given mass of the vapour at the given dryness fraction (or steam quality). In the case of wet steam it is solved for by a function of the relationship between the percentage saturated liquid, and the percentage saturated vapour in terms of specific volumes for the two obtained from a data chart.
No. Vapour does not smell.
The water vapour condensed on the windows. The vapour rising off the acid made me choke.
no
Any vapour is compressible.
Whi many are, many are not (iodine vapour is quite easily seen, for example, where water vapour is not).
Yes, patent binding, perfect binding and adhesive binding are the same thing.
As the word "vapour" indicates, it is a gas.
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.
It is called water vapour or simply vapour.
Chlorine or bromine gas would be an example of a visivle vapour.
None, except the plural in (vapour)s
The molecular mass of water vapour is 18.01528
