Air Temperature 10000 Meters

Standard atmosphere 1976 is an atmospheric model of how the pressure temperature density and viscosity of the earth s atmosphere changes with altitude it is defined as having a temperature of 288 15 k 15 o c 59 o f at the sea level 0 km geo potential height and. The air pressure at altitude 10000 m can be calculated as. Molar mass of earth s air 0 0289644 kg mol earth s atmosphere due to the fact that earth s atmosphere experiences different rates of heating and cooling through each of its layers these equations help to model this through the use of the temperature lapse rate which is the rate at which temperature changes through altitude change.

Altitude and air pressure.

Air temperature 10000 meters.

Cabin temperatures in airplanes flying at this altitude are comfortable because of air conditioners rather than heaters. The temperature you have quoted is about 5 degrees in the celsius scale. A standard atmosphere can be regarded as an average pressure temperature and air density for various altitudes. Air thermophysical properties thermal properties of air density viscosity critical temperature and pressure triple point enthalpi and entropi thermal conductivity and diffusicity and more altitude above sea level and air pressure elevation above sea level in feet and meter with barometric and atmospheric pressure inches.

The density of air varies with pressure the ideal gas law and the altitude above sea level mean absolute pressure at sea level is approximately 760 mmhg 101 325 kpa kn m 2 with a variation is about 5. P 101325 1 2 25577 10 5 10000 m 5 25588 26436 pa 26 4 kpa. The dry adiabatic lapse rate of the lower atmosphere relationship between temperature and height is about 10 celsius per 1000 meters. To answer this question let s first examine a standard atmosphere.

For all practical calculations it is taken as two degrees celsius per 1000 ft. Hpa height feet meters temperature c f 1000 200 925 150 850. Standard atmosphere heights and temperatures heights to standard pressure and temperature altitude feet pressure hpa inches temperature c f 0 1 000 2 000 3 000 4 000 5 000 6 000 7 000 8 000 9 000 10 000 11 000 12 000 13 000 14 000 15 000 16 000 17 000. The air barometer pressure varies with altitude as shown in the table below.

As a rule of thumb you can expect a drop of 0 0022 0 0023 lb cu ft 0 035 0 036 kg m per 1000 ft of altitude change. 101325 normal temperature and pressure at sea level pa p air pressure pa h altitude above sea level m example air pressure at elevation 10000 m. A find the pressure at 10 000 m and b find the temperature of the air before the air conditioner cools it off. Within the troposphere and amusing.

In the actual atmosphere the rate of variation in temperature could be erratic. The air temperature at an altitude of 10 000 meters is a chilling 35º c. If you change the air temperature humidity or the altitude and hence the pressure the air density will change too.
