What is meant by atmospheric pressure is 1 ATM?
It just means that the pressure you're measuring is approximately the same as Earth's air pressure at sea level.
How many mm of mercury in an atmosphere?
This is an old measurement, but 760 mm is one atmosphere.
Does the pressure is affected if is difference liquids?
Yes. Pressure of a liquid could be considered in two ways. 1. The subsurface pressures. 1 ATM is the pressure of our atmosphere on earth which is equivalent to a pressure of 14.7 PSI. This is the same pressure as would be exerted by 34 feet of water. So, if one dives to 34 feet, one would actually feel 2 ATM of pressure or 29.4 PSI TOTAL. However, this is the same pressure as is developed by 760mm (or 30 inches) of mercury. So a diver would feel the same 2ATM (29.4 PSI TOTAL) in less than 3 feet of Mercury. 2. Partial Pressures & Vapor Pressures. The partial pressures and vapor pressures are dependent on the type of liquid and the temperature. When the partial pressures or vapor pressures reach 1 ATM, the substance boils. So, for example, the vapor pressure of Methanol at 64.7 °C, 148.4 °F is 1 ATM, and thus it will boil. However the vapor pressure of pure water at the same pressure is significantly less than 1 ATM, and the water does not boil. This is used to distill substances. However, as with water/alcohol mixes, the water does exert a certain vapor partial pressure on the mix and one typically gets a mixture with a significant fraction of water in the final product.
What is the height of water column produces the same pressure as a 760mm high column of Mercury?
Atm
Why you say 1atm is equale to 760mm of hg while mm is the unit of length?
The pressure will support a column of mercury whose vertical height is 760mm.
What is the mean of 760mm of hg?
760 mm Hg is the standard barometric (atmospheric) pressure. It is the pressure giving a pillar of mercury (the elemental abbreviation of mercury is Hg) that is 760 millimeters (mm) high.
What is meant by atmospheric pressure is 1 ATM?
It just means that the pressure you're measuring is approximately the same as Earth's air pressure at sea level.
How many mm of mercury in an atmosphere?
This is an old measurement, but 760 mm is one atmosphere.
What is the maximum suction lift of a solid column of water?
I must assume you mean uniterrupted column of water! The maximum suction lift of a column of water is the height of a column of water (inside a vertical pipe for instance) that can be supported by atmospheric pressure i.e. approx 14.69psi or 760mm Mercury. You should be aware that suction does not cause water to lift. Suction produced by various kinds of pump merely removes air from above the column of water and this allows atmospheric pressure to act upon the base of the water column. The water column is therefore pushed upwards by atmospheric pressure from below rather than pulled up by suction from above. The density, vapour pressure and surface tension of water vary slightly with temperature and atmospheric pressure also varies slightly with weather conditions. Thus the measured height of the water column may vary slightly according to the conditions prevailing when making the measurement. A good approximation at room temperature is 33 feet or 10 metres.

Name 11 factors that should be considered when selecting a material for a product?
The temperature in a vessel is 36 degree C and the proportion by mass of air to dry saturated steam is 0.1. What is the pressure in the vessel in bar and in mm of mercury vacuum? The barometric pressure is 760mm Hg
How do you calculate corrected temperature?
Corrected Temperature = 100 - [(760mm Hg - Atmospheric Pressure) * (0.037°C/mm)]
How many millimeters of mercury equal to 760 Torr?
Equals 101,325 pascals, 101.325 kpascals, 760 mm of Mercury, and/or 1 atmosphere
How many mm Hg do you get from 0.600 ATM?
760mm Hg (standard atmospheric pressure) X .600=456 mm Hg
What is the suction pressure of condensate extraction pump?
Condensate pump suction pressure below 4 feet of the condenser is almost equal to condenser pressure (760mm of Hg). If the pump equiped under the deep pit , suction pressure is vary.
What gauge is class 5047?
760mm
