Weather: Is the Pressure Getting to You? But the inch is really not a unit of pressure, or force per area. It is a unit of length. So a metric unit has been defined to describe normal atmospheric pressure, called a bar, and the instrument becomes a barometer.. Actually, normal average sea-level pressure is 1.01325 bars, or 1,013.25 millibars (mb).The millibar is a commonly used unit of pressure.he weight of the atmosphere on the surface of the mercury exerts a pressure transmitted through the fluid, forcing it to rise. The greater the weight, the higher the rise. The barometric pressure seldom goes above 31 inches or drops below 29 inches. Normal sea-level pressure is 29.92 inches.

Hypertension JNC7 (2003) uses the term prehypertension for blood pressure in the range 120–139 mmHg systolic and/or 80–89 mmHg diastolic, while ESH-ESC Guidelines (2007) and BHS IV (2004) use optimal, normal and high normal categories to subdivide pressures below 140 mmHg systolic and 90 mmHg diastolic.he systolic pressure occurs when the left ventricle is most contracted; the diastolic pressure occurs when the left ventricle is most relaxed prior to the next contraction. Normal blood pressure at rest is within the range of 100–140 millimeters mercury (mmHg) systolic and 60–90 mmHg diastolic.

What Is Normal for Blood Pressure? Normal Blood Pressure The American Heart Association defines a normal blood pressure range for adults as systolic pressure below 120 and diastolic pressure below 80 -- or readings below 120/80 mm Hg. Blood pressure can get too low, typically a concern if readings are below 90/60 mm Hg or accompanied by symptoms such as dizziness, fainting, clammy skin, shallow breathing or fatigue. Blood pressure readings can get too high, which is a risk for long-term health problems such as heart disease, kidney failure, erectile dysfunction and stroke.

standard temperature and pressure (STP) Standard temperature and pressure, abbreviated STP, refers to nominal conditions in the atmosphere at sea level. This value is important to physicists, chemists, engineers, and pilots and navigators.Standard temperature is defined as zero degrees Celsius (0 0 C), which translates to 32 degrees Fahrenheit (32 0 F) or 273.15 degrees kelvin (273.15 0 K).This is essentially the freezing point of pure water at sea level, in air at standard pressure.Standard pressure supports 760 millimeters in a mercurial barometer (760 mmHg). This is about 29.9 inches of mercury, and represents approximately 14.7 pounds per inch (14.7 lb/in 2).Imagine a column of air measuring one inch square, extending straight up into space beyond the atmosphere.his value is important to physicists, chemists, engineers, and pilots and navigators. Standard temperature is defined as zero degrees Celsius (0 0 C), which translates to 32 degrees Fahrenheit (32 0 F) or 273.15 degrees kelvin (273.15 0 K).

- Barometers of this type can usually measure atmospheric pressures in the range between 28 and 31 inches of mercury. A barometer is commonly used for weather prediction, as high air pressure in a region indicates fair weather while low pressure indicates that storms are more likely.

Low Blood Pressure (Hypotension) Symptoms and Treatments Normal diastolic blood pressure ranges between 60 and 80 mm Hg. Current guidelines define normal blood pressure range as lower than 120/80. Blood pressures over 130/80 are considered high. High blood pressure increases the risk of damaging the arteries which leads to the development of: 1  Heart disease.

- Although aircraft cabins are pressurized, cabin air pressure at cruising altitude is lower than air pressure at sea level. At typical cruising altitudes in the range 11 000–12 200 m (36 000–40 000 feet), air pressure in the cabin is equivalent to the outside air pressure at 1800–2400 m (6000–8000 feet) above sea level.As a consequence, less oxygen is taken up by the blood (hypoxia) and gases within the body expand.t typical cruising altitudes in the range 11 000–12 200 m (36 000–40 000 feet), air pressure in the cabin is equivalent to the outside air pressure at 1800–2400 m (6000–8000 feet) above sea level.

What is the air pressure at sea level? Unfortunately for the student, there are many, many different units for measuring atmospheric pressure. Standard air pressure at sea level is most easily defined as 1 atmosphere, or 1 atm. In terms of an international (ISO) standard, it is defined to be 101325 Pa or 101.3 kPa (kilo-Pascals) at a temperature of 15 °C.

What is the barometer readings? waht is normal? Best Answer: Barometric readings show what the barometric pressure or air pressure is. Air pressure is the force exerted on you by the weight of tiny particles of air.Barometers are used to measure the current air pressure at a particular location in inches of mercury or in millibars (mb).A measurement of 29.92 inches of mercury is equivalent to 1013.25 millibars.f a high pressure system is on its way, often you can expect cooler temperatures and clear skies. If a low pressure system is coming, then look for warmer weather, storms and rain. Average sea-level pressure is 29.921 inches of mercury. As altitude increase, air pressure decreases.

What is the barometer readings? waht is normal? A barometer measures atmospheric pressure. It is measured in various units, one of the oldest being inches of mercury. Other units include pounds per square inch (PSI) kilo-Pascals (kPa) and atmospheres (ATM). Standard pressure is 29.92 inches of mercury, 14.7 PSI, 100 kPa or 1 ATM. Lower barometer readings are generally associated with less stable weather (as in, low pressure system), while higher ones are generally associated with more stable weather (as in, high pressure system).
