The standard atmosphere (symbol: atm) is a unit of pressure and is defined as being precisely equal to 101.325 kPa. It is equivalent to 760 mmHg (torr) or 29.92 inHg. One standard atmosphere is standard pressure used for pneumatic fluid power (ISO R554), and in the aerospace (ISO 2533) and petroleum (ISO 5024) industries.

What does Hg stand for in the metric system?
Nothing.Hg is the chemical symbol for Mercury and, under the old system, atmospheric pressure was measured in terms of the height of a column of mercury that it could support. In the SI systems this has been replaced by pressure measured in Pascals. Standard atmospheric pressure is 101325 Pa.
High air pressure in a freightliner?
Air pressure governor needs to be replaced.
When low pressure is replaced by high pressure what happens?
Low pressure systems generally have bad weather and high pressure systems make for good weather!
What would the weather be like if you replaced a low pressure system with a high pressure system?
the area would become cooler with less humidity
Which type of weather is most often associated with fluffy white clouds?
How would weather conditions in an area change if a high pressure system replaced a low pressure

Can you make a homemade barometer that works?
It will be difficult as the hose is opaque making reading it visually impossible.You will need roughly 30 feet of hose suspended vertically above the bucket with the top end sealed shut and filled with water.
How does a barograph work?
A barograph is a device used to monitor pressure. It is a recording aneroid barometer and uses a pen instead of a pointer to record the data.
What is a device for measuring atmostpheric pressure?
The most usual devices are barographs and barometers. A barometer can work off an aneroid cell (eg digital aneroid barometer) or a column of mercury (eg Kew Pattern barometer). Barographs usually work off aneroid cells and through a linkage system print the pressure onto a chart (usually changed weekly although there are daily barometers as well). So the main difference is that a barometer gives a spot reading while the barograph is continuous, although it's possible for the readings from a digital barometer like one connected to an Automatic Weather Station to be saved and called up later, or even printed out in graph form. The usual unit for air pressure in meteorological circles is the hectoPascal (hPa) which replaced the millibar some years ago (the units have the same numerical value, though) except for the US which sticks with the old inches of mercury (InHg).

Can you replace the abs unit with a pressure metering valve?
i have no peddle pressure and i already replaced the master cylinder

Why does the vacuum braker leak a little water when the water spray is truned on in a salon sink?
A vacuum breaker should not leak at all. The purpose of the vacuum breaker is to control the atmospheric pressure inside a geyser. If it is leaking, it means the rubber seal inside has either broken or has perished and needs to be replaced.
What happens when the mercury in barometer or manometer is replaced by water or any other less dense liquid than water?
Since water is lighter than mercury, this means the height will differ. The denser (high relative density) the fluid, the shorter the height. If the fuild is light such as water its height will be much higher than that of mercury. Also, the denser the material is the higher the pressure.
Clutch stuck to pressure plate how do repair it?
The clutch will have to be replaced. The pressure plate could possibly be resurfaced but usually it is as cost effective to replace the pressure plate.
How do you convert absolute pressure to gauge pressure?
The pressure in a fluid is defined as"the normal force per unit area exerted on a imaginary or real plane surface in a fluid or a gas"The equation for pressure can expressed as:p = F / A (1)wherep = pressure [lb/in2 (psi) or lb/ft2 (psf), N/m2 or kg/ms2 (Pa)]F = force [1), N]A = area [in2 or ft2, m2]1) In the English Engineering System special care must be taken for the force unit. The basic unit for mass is the pound mass (lbm) and the unit for the force is the pound (lb) or pound force (lbf).Absolute PressureThe absolute pressure - pa - is measured relative to the absolute zero pressure - the pressure that would occur at absolute vacuum. All calculation involving the gas laws requires pressure (and temperature) to be in absolute units. Gauge PressureA gauge is often used to measure the pressure difference between a system and the surrounding atmosphere. This pressure is often called the gauge pressure and can be expressed as pg = ps - pa (2)wherepg = gauge pressureps = system pressurepa = atmospheric pressureAtmospheric PressureAtmospheric pressure is pressure in the surrounding air at - or "close" to - the surface of the earth. The atmospheric pressure vary with temperature and altitude above sea level. Altitude and Air DensityStandard Atmospheric PressureStandard Atmospheric Pressure (ATM) is used as a reference for gas densities and volumes. The Standard Atmospheric Pressure is defined at sea-level at 273oK (0oC) and is 1.01325 bar or 101325 Pa (absolute). The temperature of 293oK (20oC) is also used.In imperial units the Standard Atmospheric Pressure is 14.696 psi.1 ATM = 1.01325 bar = 101.3 kPa = 14.696 psi (lbf/in2)= 760 mmHg =10.33 mH2O = 760 torr = 29.92 inHg = 1013 mbar = 1.0332 kgf/cm2 = 33.90 ftH2OPressure UnitsSince 1 Pa is a small pressure unit, the unit hectoPascal (hPa) is widely used, especially in meteorology. The unit kiloPascal (kPa) is commonly used design of technical applications like HVAC systems, piping systems and similar. 1 hectoPascal = 100 Pascal = 1 millibar1 kiloPascal = 1000 PascalSome Pressure Levels10 Pa - the pressure below 1 mm of water1 kPa - approximately the pressure exerted by a 10 g of mass on a 1 cm2 area10 kPa - the pressure below 1 m of water, or the drop in air pressure when moving from sea level to 1000 m elevation10 MPa - nozzle pressure in a "high pressure" washer10 GPa - pressure enough to form diamondsSome Alternative Units of Pressure1 bar - 100,000 Pa1 millibar - 100 Pa1 atmosphere - 101,325 Pa1 mm Hg - 133 Pa1 inch Hg - 3,386 PaA torr (torr) is named after Torricelli and is the pressure produced by a column of mercury 1 mm high - equals to 1 / 760th of an atmosphere.1 ATM = 760 torr = 14.696 psiPounds per square inch (psi) was common in U.K. but has now been replaced in almost every country except in the U.S. by the SI units. Since atmospheric pressure is 14.696 psi - a column of air on a area of one square inch area from the Earth's surface to the space - weights 14.696 pounds.The bar (bar) is common in the industry. One bar is 100,000 Pa, and for most practical purposes can be approximated to one atmosphere even if1 Bar = 0.9869 ATMThere are 1,000 millibar (mbar) in one bar, a unit common in meteorology.1 millibar = 0.001 bar = 0.750 torr = 100 Pa
