∙ 7y agoStandard atmospheric pressure is 101.325 kPa. It can also be quoted as 760 mm Hg, or 14,696 psi. Many values of atmospheric pressure are normal, because it varies all the time, but the average at sea level is 101.325 kPa.

What is the atmospheric pressure?
Atmospheric pressure is the weight of the air above you. this weight is 14.7 lbs per square inch at sea level. Air is made up of 78% Nitrogen - 21% oxygen and 1% trace gasses at sea level, This changes as you ascend as oxygen thins out and other gasses take its place which are lighter than air this changes the partial pressures of the gasses and of cores the weight.
What is the partial pressure of oxygen in a balloon?
The partial pressure of oxygen will vary according to where you look. Atmospheric oxygen partial pressure is approximately 21% of the atmospheric pressure of the location at which you measure (typically around 1 atmosphere at sea level, making the partial pressure of oxygen at seal level 0.21 ATM or 21.3KPa). The value varies geographically and with time, but also varies in different tissues of organisms, since not all oxygen available is absorbed, and complex multicellular organisms will have certain tissues (respiring muscle) that use up oxygen, resulting in a lower partial pressure there.normal oxygen partial185.4 kPa or in another unit:100 mmHg in the arterial blood. The partial pressure on the alveolar site is about 105 mmHg.
How would the altitude and the atmospheric pressure of Johannesburg affect the boiling point of water?
The boiling point of water decrease when the altitude increase; the value at Johannesburg is near 94 0C.
Atmospheric pressure in context of sound?
The instantaneous sound pressure is the deviation from the local ambient pressure po caused by a sound wave at a given location and given instant in time. The effective sound pressure is the root mean square of the instantaneous sound pressure over a given interval of time (or space). Total pressure is given by: p-total = po + p-osc where: po = local ambient atmospheric (air) pressure, p-osc = sound pressure deviation. The standard atmosphere is a unit of pressure and is defined as being equal to po = 101325 Pa. Sound pressure level (SPL) or sound level is a logarithmic measure of the effective sound pressure of a sound relative to a reference value. It is measured in decibels (dB) above a standard reference level. The commonly used reference sound pressure level in air of 0 dB is equivalent to the sound pressure of p = 20 µPa RMS, which is usually considered the threshold of human hearing at 1 kHz. The threshold of of pain has a level of about 137.5 dB equivalent to a sound pressure of 150 Pa.
What is cohesion value of clay?
The cohesion value of clay is its shear strength under conditions of no confining pressure.
The value of atmospheric pressure at Johannesburg?
85 kPa
What is absolute pressure?
Absolute pressure is simply the addition of the observed gage pressure plus the value of the local atmospheric pressure.
What is the value of atmospheric pressure?
about 100,000 newton per metre square. =)
Why do the lungs remain expanded in the normal thoracic?
A couple of reasons: surfactant - a detergent - reduces surface tension to a negative value. the plura contains a "vacume" (lower pressure than atmospheric) and pulls the lungs to the chest wall. venous blood partial gas pressure is sub atmospheric.
If the absolute pressure of gas is?
Absolute pressure is simply the addition of the observed gage pressure plus the value of the local atmospheric pressure.
What is the value for normal blood pressure?
The value of normal blood preasure is 120/80.
Normal blood pressure value is 140 90mm Hg true or false?
False, normal blood pressure is a value of 120/80 mm Hg or lower.
What is the normal value of coronary perfusion pressure?
15-70
How does the percent of oxygen and nitrogen change with the increase in altitude?
When the altitude increases, the air becomes thinner. There are fewer air molecules at 60 km above the surface than 30 km. Thinner air has less air molecules because they are further apart. In dense air, the molecules are packed tighter.

What is blood pressure and what is the normal value of a healthy blood pressure?
less than 120 over 80
What is the PO2 of the alveoli?
Normal atmospheric pressure of air is 150 mm Hg for oxygen (around 610 mm Hg for nitrogen). This equals 760 mm Hg in the atmosphere. In the alveoli, however, pressure is lower because 30% is being used by tissues, leaving 70% of 150 mm Hg oxygen in the alveoli. That means around 100-105 mm Hg is the partial pressure of oxygen in alveoli.
