# What is the temp at sea level?

59°FIn the ISA model, the standard sea levelstandard sea levelStandard sea-level conditions (SSL), also known as sea-level standard (SLS), defines a set of atmospheric conditions for physical calculations.

## What was the temperature at sea level at 20000 ft?

So, while your standard temperature at msl is 15° C or 59° F, your standard temperature at 20,000 feet msl will be -24.6°C or -12.3°F.

## What is standard sea level temperature pressure?

Altitude variation

Parameter Description Value
p0 Sea level standard atmospheric pressure 101325 Pa
L Temperature lapse rate, = g/cp for dry air ~ 0.00976 K/m
cp Constant-pressure specific heat 1004.68506 J/(kg·K)
T0 Sea level standard temperature 288.16 K

## What is the air at sea level?

Standard sea-level pressure, by definition, equals 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch, 1,013.25 × 103 dynes per square centimetre, 1,013.25 millibars, one standard atmosphere, or 101.325 kilopascals.

## What is the temperature at 6000 feet?

Standard Atmospheric Conditions

Altitude (feet) Pressure (in. Hg) Temp. (F°)
sealevel 29.92 59.0
2,000 27.82 51.9
4,000 25.84 44.7
6,000 23.98 37.6

## At what height is there no oxygen?

26,000 ft

It refers to altitudes above a certain point where the amount of oxygen is insufficient to sustain human life for an extended time span. This point is generally tagged as 8,000 m (26,000 ft, less than 356 millibars of atmospheric pressure).

## Is there oxygen at 35000 feet?

Natural availability of oxygen at 35,000 feet
In other words, there’s ample air at 35,000 feet, and there is sufficient oxygen in it. In fact, there’s even a reasonable amount of air at the altitude where the International Space Station operates!

## How much does the temperature drop for every 1000 feet of elevation?

3.5 degrees Fahrenheit

You will lose an average 3.5 degrees Fahrenheit for every 1000 feet of elevation you gain. You can also use about 1.2 degrees Celsius per ever 1000 feet, or about 1 degree Celsius per 100 meters (source, NFW who showed me my typo on the metric conversion in the comments).

## What is sea level value?

= 12.014 N/m3 ⇔ 0.07647 lbf/ft.

## How do you find the temperature at altitude?

NASA supplies a formula that calculates the expected stratospheric temperature (T in degrees C) given the global average temperature of -57 degrees C at 25 km altitude. The formula is T = -131 + (0.003 * altitude in meters).

## How cold is it in space?

The Cosmic Background Explorer (COBE) satellite has refined temperature measurements taken way back in 1964. According to data from the Cosmic Background Explorer (COBE) satellite, the temperature of space is 2.725K (2.725 degrees above absolute zero).

## What is the temperature on the moon?

Taking the Moon’s Temperature
Daytime temperatures near the lunar equator reach a boiling 250 degrees Fahrenheit (120° C, 400 K), while nighttime temperatures get to a chilly -208 degrees Fahrenheit (-130° C, 140 K). The Moon’s poles are even colder.

## How cold is it at 33000 feet?

Between 9,000 and 12,000 metres (30,000 and 40,000 feet), the cruising altitude of most jet aircraft, air temperatures range from −40 to −70 °F (−40 to −57 °C). Modern aircraft have sealed cabins and heaters to protect pilots and passengers from wind blasts and cold air.

## Why do planes not freeze in the air?

At an altitude of 35,000 feet, however, the clouds are made of ice crystals so no supercooled droplets exist thus, airplanes do not face icing issues.

## How far can a pilot see at 35000 feet?

At 35,000 Feet: You can see 228 miles from a height of 35,000 feet. At 40,000 Feet: You can see 244 miles from a height of 40,000 feet.
