Pressure measurement - Wikipedia

If you work with pressure, you know that it is very common that a pressure is indicated with certain pressure unit and you need to convert it into another pressure unit.  Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.:445 Gauge pressure (also spelled gage pressure)..

This includes Absolute Pressure (AP), Gauge Pressure, and Differential Pressure. If you'd like more info on absolute pressure, check out an article about pressure from Wikipedia Pressure, in the physical sciences, perpendicular force per unit area, or the stress at a point within a The absolute pressure exerted by the air within the tire, including atmospheric pressure, is 45.. Also, the temperature of the liquid effects to the density of the liquid and that also effects slightly the readings of a U-tube. There are various different liquid column based pressure units available, having the liquid temperature specified in the pressure unit, most commonly used temperatures are 0 °C, 4 °C, 60 °F, 68 °F. But there are also water column units, which have no indication of the water temperature. These are based on a theoretical density of water, being 1 kg/1 liter (ISO31-3, BS350). In practice, the water never has that high density. The highest density that water have is at +4 °C (39.2 °F) where it is approximately 0.999972 kg/liter. The density of water gets lower if the temperature is higher or lower than +4 °C. Temperature can have a pretty strong effect on the density, for example going from +4 °C to +30 °C changes the waterdensity about 0.4%.

Some meteorologists prefer the hectopascal (hPa) for atmospheric air pressure, which is equivalent to the older unit millibar (mbar). Similar pressures are given in kilopascals (kPa) in practically all other fields, where the hecto prefix is hardly ever used. In Canadian weather reports, the normal unit is kPa. The obsolete unit inch of mercury (inHg) is still sometimes used in the United States. Pressure (Japanese: プレッシャー Pressure) is an Ability introduced in Generation III.

As a manufacturer of efficient high-pressure pumps and high-pressure technology, URACA provides tailor-made solutions for safe and economical production and cleaning processes Pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. The pressure exerted on a floor by a 42-pound box the bottom of which has an area of 84 square inches is equal to the force divided by the area over which it is exerted; i.e., it is one-half pound per square inch. The weight of the atmosphere pushing down on each unit area of Earth’s surface constitutes atmospheric pressure, which at sea level is about 15 pounds per square inch. In SI units, pressure is measured in pascals; one pascal equals one newton per square metre. Atmospheric pressure is close to 100,000 pascals.

Back to water column: It is clear that when the length indication was made to a U column, many different length units have been used, both metric and non-metric. This has generated many different pressure units.SI system is the world’s most widely used system of measurement. It was published in 1960, but has a very long history even before that.

A kernel with this patch set applied will have a new virtual directory called /proc/pressure containing three files It is good to notice that in practice the “force” is not always included in the pressure unit names. For example pressure unit kilogram force per square centimeter should be indicated as kgf/cm², but often it is indicated just as kg/cm² without the “f ”. Similarly, pound force per square inch (pfsi) is normally indicated as pounds per square inch (psi).The abbreviation “cgs” comes from words “centimetre-gram-second”. As these words hints, the cgs system is a variation of metric system, but instead of using the meter it uses centimeter as the unit for length, and instead of kilogram it uses gram as the unit for mass. Different cgs mechanical units are derived from using these cgs base units.

Density depends on pressure, but what exactly is pressure? Pressure is simply the force experienced by an object divided by the area of the surface on which the force acts Pressure is still sometimes expressed in kgf/cm² or grams-force/cm² (sometimes as kg/cm² and g/cm² without properly identifying the force units). But using the names kilogram, gram, kilogram-force, or gram-force (or their symbols) as a unit of force is expressly forbidden in SI; the unit of force in SI is the newton (N). The technical atmosphere (symbol: at) is 1 kgf/cm².

Low blood pressure might seem desirable, and for some people, it causes no problems. The causes of low blood pressure can range from dehydration to serious medical disorders The ambient pressure on an object is the pressure of the surrounding medium, such as a gas or liquid, in contact with the object. Within the atmosphere, the ambient pressure decreases as height increases. By measuring ambient atmospheric pressure, a pilot may determine altitude (see pitot-static system)


Pressure units are based on standards and the conversion between units should also be based on standards. Most common standards for pressure units are:In countries using Imperial system (like USA and UK), the engineering units used both for mass and area are different than with SI system. Therefore this also creates a whole new set of pressure units. Mass is being measured commonly in pounds or ounces, and area and distance with inches or feet.So some pressure units derived from these are lbf/ft², psi, ozf/in², iwc, inH2O, ftH2O.The cgs is pretty old system and has been mostly replaced first by the MKS (meter-kilogram-second) system which then has been replaced by the SI system.

Although a liquid column sounds very simple, it is important to remember that the weight of the liquid depends on the local gravity, so if you calibrate the column in one place and take it to another (distant, different elevation) place, it may not be measuring correctly anymore. So gravity correction is needed to be precise."Pressure is a scalar quantity, but teachers and authors do not appear to believe this in their hearts." (McClelland, 1987)

pressure [ˈpreʃə]Существительное. pressure / pressures Hydrostatic pressure is the stress, or pressure, exerted equally in all directions at points within a confined fluid (liquid or gas). It is the only stress possible in a fluid at rest. See Pascal’s principle.Another pressure unit used for measuring atmospheric absolute pressure is torr, being 1/760 of standard atmosphere. So torr is an absolute pressure, although that is typically not mentioned, you just need to know it, which can cause confusion. Torr was initially meant to be the same as 1 millimeter of mercury, although the later definitions show a very small difference in between. Torr is not part of the SI system. Air pressure is measured with mercury or aneroid barometers. Air pressure is not uniform across the planet, however. The normal range of the Earth's air pressure is from 970 MB to 1,050 MB Stagnation pressure is the pressure a fluid exerts when it is forced to stop moving. Consequently, although a fluid moving at higher speed will have a lower static pressure, it may have a higher stagnation pressure when forced to a standstill. Static pressure and stagnation pressure are related by the Mach number of the fluid. In addition, there can be differences in pressure due to differences in the elevation (height) of the fluid. See Bernoulli's equation.

Although the SI system is used in most of the countries, there is still a lot of other pressure units also being used. So let’s take a look at those next.If you remember the studies of physics in school … as most of us don’t remember… a short reminder is in order: pressure is defined as force per area perpendicular to the surface.

Pressure is kind of like force, but not quite The older pressure measurement devices were often made by using liquid in a transparent U-tube. If the pressure in both ends of the tube is the same, the liquid level in both sides are on the same level. But if there is a difference in the pressures, then there is a difference in the liquid levels. Level difference being linearly proportional to the pressure difference. In practice you can leave one side of the tube open to the room’s atmospheric pressure and connect the pressure to be measured to the other side. As referred to the current atmospheric pressure, it is a gauge pressure type being measured.

Pressure is sometimes measured, not as an absolute pressure, but relative to atmospheric pressure; such measurements are sometimes called gauge pressure. An example of this is the air pressure in a car tire, which might be said to be "220 kPa," but is actually 220 kPa above atmospheric pressure. Since atmospheric pressure at sea level is about 100 kPa, the absolute pressure in the tire is therefore about 320 kPa. In technical work, this is written "a gauge pressure of 220 kPa." Where space is limited, such as on gauges, name plates, graph labels, and table headings, the use of a modifier in parentheses, such as "kPa (gauge)" or "kPa (absolute)," is permitted. In non-SI technical work, a gauge pressure is sometimes written as "32 psig," though the other methods explained above that avoid attaching characters to the unit of pressure are preferred. 1 Pressure Relief Valve (PRV) is a safety valve used to limit pressure in a system, otherwise pressure will build up and create process upset Pressure.

Let us look at a static gas, one that does not appear to move or flow. While the gas as a whole does not appear to move, the individual molecules of the gas, which we cannot see, are in constant random motion. Because we are dealing with an extremely large number of molecules and because the motion of the individual molecules is random in every direction, we do not detect any motion. If we enclose the gas within a container, we detect a pressure in the gas from the molecules colliding with the walls of our container. We can put the walls of our container anywhere inside the gas, and the force per unit area (the pressure) is the same. We can shrink the size of our "container" down to an infinitely small point, and the pressure has a single value at that point. Therefore, pressure is a scalar quantity, not a vector quantity. It has a magnitude but no direction associated with it. Pressure acts in all directions at a point inside a gas. At the surface of a gas, the pressure force acts perpendicular to the surface. The most commonly used liquid in the column was obviously water. But in order to be able to measure higher pressure with smaller U-tube, heavier liquids were needed. One such liquid is mercury (Hg) as it is much heavier than water (13.6 times heavier). When you use heavier liquid you don’t need to have that long column to measure higher pressure, so you can make a smaller and more convenient size column. For example, blood pressure was earlier (still sometimes is) measured with a mercury column. Mercury is mainly used because a water column for same pressure range would be so long it would not be practical to use it in a normal room, as water column is about 13.6 times longer than mercury column. As a result of this, even today the pressure unit that blood pressure is typically expressed is millimeter of mercury (mmHg).

The ambient pressure on an object is the pressure of the surrounding medium, such as a gas or liquid, in contact with the object.[1] Finally, the readability of a mechanical liquid column is typically pretty limited, so you can’t get very accurate measurements. And due to the mechanical limitations, you can’t use a U-tube for high pressure. All of these above mentioned issues makes a U-tube liquid column not very practical to use. Also, modern digital pressure measurement devices have replaced the liquid columns. But many of the pressure units created in the era of liquid columns have remained and are still used today.

Measurement of pressures by ordinary gauges on Earth, such as a tire-pressure gauge, expresses pressure in excess of atmospheric. Thus, a tire gauge may indicate a pressure of 30 pounds (per square inch), the gauge pressure. The absolute pressure exerted by the air within the tire, including atmospheric pressure, is 45 pounds per square inch. Pressures less than atmospheric are negative gauge pressures that correspond to partial vacuums.The pressure of a moving fluid can be measured using a Pitot probe, or one of its variations such as a Kiel probe or Cobra probe, connected to a manometer. Depending on where the inlet holes are located on the probe, it can measure static pressure or stagnation pressure. Blood pressure is still measured in millimetres of mercury in most of the world, and lung pressures in centimeters of water are still common. These obsolete manometric units of pressure are based on the pressure exerted by the weight of some "standard" fluid under some "standard" gravity. They are effectively attempts to define a unit for expressing the readings of a manometer. When millimetres or inches of mercury are used today, they have precise definitions that can be expressed in terms of SI units. The water-based units depend on the density of water, a measured, rather than defined, quantity. It is the pressure resulting from a force of one pound-force applied to an area of one square inch. The pascal (symbol Pa) is the SI unit of pressure.It is equivalent to one newton per square metre Use our blood pressure chart to learn what your blood pressure levels and numbers mean.

Pressure is the measure of force acting on a unit area. Density is the measure of how closely any given entity The pressure and density relationship for ideal gases and fluids is mathematically written a High blood pressure, or hypertension, rarely has noticeable symptoms. The systolic pressure (higher number) is the force at which your heart pumps blood around your body
