If mercury was replaced by water in a barometer how high a column would correspond to the normal atmospheric pressure?
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 In the SI systems this has been replaced by pressure measured in Pascals.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.
When low pressure is replaced by high pressure what happens?
When low pressure is replaced by high pressure, air flows from the high pressure area to the low pressure area. This movement of air causes winds to form as the atmosphere seeks to achieve equilibrium. The change in pressure can also lead to changes in weather conditions, with high pressure typically associated with fair weather and low pressure with unsettled conditions.
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
What kind of weather is most likely to occur when low pressure air moved off to the east and was replaced by high pressure air form the west?
When low pressure air moves east and is replaced by high pressure air from the west, it typically brings clear skies and cooler weather. This is because high pressure systems often result in descending air, which suppresses cloud formation and leads to stable weather conditions. Additionally, the air coming from the west may be drier, further contributing to the clear and cool conditions.
How has the Barometer changed over the Years?
The Barometer, traditionally used to measure atmospheric pressure, has evolved significantly over the years with advancements in technology. Early mercury barometers were replaced by aneroid barometers, which use metal chambers to measure pressure changes more safely and compactly. Modern digital barometers now incorporate sensors and can provide real-time data, offering greater accuracy and ease of use. Additionally, the integration of barometric data into weather forecasting and climate studies has enhanced our understanding of atmospheric phenomena.

How does a barograph work?
A barograph is an instrument used to record the atmospheric pressure over time. It works by using a stack of aneroid capsules that expand or contract in response to changes in pressure. As these capsules move, they cause a pen attached to a lever to move up and down, recording the pressure changes on a rotating drum coated with paper.
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 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.
Why does the air pressure in a straw be reduced when sucked?
when u suck from a straw (no offense lol) u r taking air from it and it is not replaced by any so pressure starts to decrease ..... when it gets stronger it pulls liquid(being heavier than air!) but when cup is empty no pressure decrease as air is replaced by air.
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.
What is a blood pressure dinamap?
a blood pressure measuring device that largely replaced sphygmomanometers
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.
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.
When low pressure is replaced by high pressure what happens?
When low pressure is replaced by high pressure, air flows from the high pressure area to the low pressure area. This movement of air causes winds to form as the atmosphere seeks to achieve equilibrium.
