I'm going to assume you mean underwater.The weight of a column of air from sea level to outer space is about the same as the weight of a column of water the same size 32 feet high. This is called "one atmosphere" of pressure.

So, to find out the pressure at any depth, we just divide the depth by 32 feet to get the pressure in atmospheres. At 26000 feet, this amounts to 812.5 atmospheres... plus the one from the atmosphere itself, of course. This amounts to about 12000 pounds per square inch.

The pressure at 26,000 feet below sea level can be calculated using the hydrostatic pressure formula: P = ρgh, where P is the pressure, ρ is the density of the fluid (sea water), g is the acceleration due to gravity, and h is the depth. At this depth, the pressure would be approximately 799 atmospheres or about 11,700 pounds per square inch (psi). This high pressure is due to the weight of the water column above exerting force on the fluid below.

35000ft equals 10668 meters.

Assuming water density at 1000kg/m3, the pressure equals p = density * g * h + patmospheric.

Result is:

10668 * 9,81 * 1000 + 101325 Pa= 104,7 MPa.

Approximately 380 hPa (mb). In contrast, average sea level pressure is around 1013 hPa (mb).

Elevation and atmospheric pressure have a direct correlation. The higher the elevation, the lower the pressure. At 2500 feet above sea level, the pressure is about 78 kpa.

5000 Feet=1524Meters

Pressure=(rho)gh

Rho=Density=1000

g=9.81

h=height=1524

Pressure=1000x9.81x1524

=14950440Pa

=15MPa

Immense. At 35,000 feet of water depth the pressure is about 1,032.5 atmospheres.

A compound pressure gauge for the low side of the system measures pressure in what?

A compound pressure gauge measures two scales, one in positive pressure and one in negative (below atmospheric) pressure or vacuum positive pressure is measured in pounds per square inch (psi) or kilopascals or in some cases bars (1 bar = 14.35 psi) [ the average atmospheric pressure at 1000 feet above sea level] vacuum is measured in millimeters of mercury mmHg or inches of mercury inHg


The absolute pressure in the ocean at 53 feet is?

53 feet = 16.154 4 meterthe water pressure at 16.154 4 meters = 1.61544 bars + 1 bar of atmospheric pressure makes the absolute pressure = 2.62 bars.


In 20000 feet under the ocean what is the number of pressure per square inch?

In a depth of 20,000 feet there is 5 tons per square inch of pressure.


The free atmosphere lies above what height?

The top of the atmosphere is not well defined. Rather, the gases (primarily nitrogen and oxygen) comprising the atmosphere gradually thin the higher one goes. Air pressure is 100 kPa at sea level (14.7 psi) and falls to 50 kPa (7.25 psi) about a mile above sea level. Half the weight of the atmosphere is within the first 3.5 miles (18,000 feet) of sea level. At 15,000 feet (3 miles above sea level) atmospheric pressure drops to 10 kPa (1.5 psi). 90% of the atmosphere is below 52,000 feet (10 miles). There is still enough air to support jet aircraft above 30,000 feet, and high altitude balloons will ascend to over 100,000 feet (nearly 20 miles). At 20 miles above the earth the day time sky turns quite black, and you can see the hazy boundary between air and space. For most purposes you could say it ranges anywhere from 20 to 100 miles.


What does 5 ATM mean on a wrist watch?

"ATM" stands for ATMospheres and the number before it, refers to the number of atmospheres of pressure the watch will withstand before leaking. At sea level we are all subjected to one atmosphere of pressure, because we have one atmosphere of air above us pressing down. For every 33 feet (10 metres) underwater you go, the pressure increases by 1 atmosphere. Therefore, at 33 feet underwater the pressure is 2 atmospheres (2 ATM), at 66 feet underwater the pressure is 3 atmospheres (3 ATM), etc. So 5 ATM is equivalent to 132 feet (40 metres) underwater. In conclusion, the ATM rating of a watch is the number of atmospheres of pressure the watch will withstand before breaking/leaking. To convert ATM 's into the depth rating in metres just subtract 1 and multiply by 10. eg: 5 ATM = (5 - 1)*10 = 40 metres.

What is the Pressure at 1200 feet below sea level?

The pressure at 1200 feet below sea level is approximately 517.2 pounds per square inch (psi). This value is calculated using the formula: pressure = depth × density of seawater × acceleration due to gravity.


Is the speed of sound louder at 300 feet below sea level than at 200 feet?

The speed of sound in water is affected by temperature, salinity, pressure, and depth. Typically, the speed of sound increases with depth due to increased pressure, so it is likely louder at 300 feet below sea level compared to 200 feet.


Which is a higher elevation 40 feet below sea level or 14 feet below sea level?

40 feet below sea level is at a higher elevation than 14 feet below sea level. Elevation is measured by the distance above or below a reference point, such as sea level, so the higher the number below sea level, the lower the elevation.


What is 2.75 meter below sea level in feet?

Which is higher 5 feet below sea level or 4 feet below sea level?

5 feet below sea level is higher. Because if you have 5 feet below sea level then you go from the average height if the top of the water and go 5 feet under it, and if you have 4 feet below sea level then you go from the average height if the top of the water and go 4 feet below, so 4 feet is higher.
