Clarification: I am wanting to know how much vacuum I need to pull to get water to boil at 150 degrees.
In a vacuum, there is no atmospheric pressure to keep the water in the liquid state.
sea water boil at 105 c
when lipui water is exposed to 32 f it
Boil the water...
You get rainfall water and boil it. Or strain and boil freshwater. Also, there's chemicals you can use.
About 100oC
If the vacuum pump is on, the water will continue to boil. If the vacuum pump is off as the vessel is sealed, the boiling will stop at a point of equilibrium.
vacuum is measured in inches of mercury. sea level is zero. water will boil at 212F. as negative pressure or elevation increases the boiling temp. of water decreases. if you had a pressure reading of 29.7 in" of mercury the water will boil at 192F. if you had a pressure reading of 10 in" of mercury water will boil at 32F
Vacuum
The amount of heat needed to boil water varies with the air pressure. Water in a vacuum will boil at room temperature.
Place the container of water in a vacuum & it should start to boil at room temperature.
The purpose of the vacuum in the fresh water generator it can make a 50 degrees Celsius boil the water that's why they create a
Choose a vacuum pump with a 29.75 hg that makes water boil 1 degree C. The typical boiling point of water is hundred degrees Celsius.
YesThis is because boiling is caused by the liquid water turning to gas which is not influenced directly by other materials. However, once in a vacuum the pressure is so low that the water will boil at much lower temperatures.
The water will boil (no calculations necessary, but look at a table that shows the vapor pressure of water at different temperatures.here's a link: http://en.wikipedia.org/wiki/Vapour_pressure_of_water )
Roughly 16 inches before the surface starts to boil from the vacuum, this is also assuming 33 degree water, the higher the water temp the less lift will be achieved due to water's vapor pressure.
Warm sea water, in an open system, is pumped into a vacuum chamber so that it will boil, and the resultant steam will drive the electricity turbines.
in order to boil water you need to heat it, so its the same thing
