absolute pressure of liquid = atmospheric pressure (P₀) + (relative density (ρ) of liquid x height of liquid x gravitational acceleration)
P₀ = 103000 Pa
ρ of sea water at 15°C = 1025 kg/m³
h = 55 m
g = 9.81m/s²
Answer = 103000 Pa + (1025 kg/m³ x 9.81 m/s² x 55 m)
Answer = 6.56 x 10^5 Pa
(Sorry about using the carat in signifying the scientific notation, but apparently I cannot find a way to type a superscript 5 using code.)
"mm Hg" stands for millimetres of mercury. Atmospheric pressure was measured in terms of the height of a column of mercury that it could support and by extension, mm Hg became a unit for measuring pressure.
Atmospheric pressure is measured by a barometer and expressed in millibars. Normal atmospheric pressure at sea level is 1,013 millibars. Pressure is also measured in pascals, which is the pressure of 1 newton over 1 square meter. (A newton is the amount of force needed to accelerate 1 kilogram by 1 meter per second per second. 'atmosphere' itself is a unit , abbreviated as atm. 1atm=1.013 x 105. In the English system, pressure is measured in pounds per square inch. A pound per square inch is equal to about 6,890 pascal.
boost is pressure. units of pressure is pounds per square inch(psi), atmospheres (bar), and kilo pascals (kpa)
Pressure is measured in Pascals. 1 Pa = 1 N/m2.
Pascal is an alternative unit of pressure to atmospheres. 1atm is 101325pa
1 atm(atmospheric pressure)=101,325pa(pascals)
Atmospheric pressure is around 101325 pascals. Usual talking is around 0.04 pascal. You see what is larger.
Gauge pressure is what you get when you take the reading from your tire pressure gauge. Absolute pressure is the pressure inside your tires plus the atmospheric pressure, which is roughly; 14.7 psi, 101.3 kPa (kilo-Pascals), or one atmosphere. Absolute pressure measures all of the pressure on your tires, inside and out, whereas gauge simply measures the pressure inside the tire.
It is an definition by the international organization. When the temperature is 15 centigrade degree. To measure the atmospheric pressure is 1013.25 hundred pascals.
About 600 pascals. For comparison, standard atmospheric pressure on Earth is about 101 kilopascals.
pressure is force divided by area. If area is 1.6m^2 then pressure is 560/1.6 = 350 pascals
One thousand pascals. A pascal is a unit of atmospheric pressure or pressure generally. There is about 7 kilopascals in one psi. The atmospheric pressure at sea level is approximately one hundred kilopascals.
Millibars. Inches of mercury or feet of water
Almost zero. Pluto has very little gravity and cannot support much of an environment. In its summer, it can get up to 0.3 Pascals of atmospheric pressure, about 338,000 times less pressure than on Earth.
hPa stands for Hectopascal preasure unit this is the international unit for measuring atmospheric or barometric pressure.1 hPa = 100 pascalsStandard atmospheric pressure = 101325 pascals = 1013.25 hPa
In the room will usually be the same as the outside atmospheric pressure. The standard atmosphere is defined as being 101325 pascals = 101.325 kPa.
The conversion factor is 101.325. So, atmospheres x 101.325 = kilo-pascals.
