Human relationship Between Altitude and Pressure

The post-obit tabular array and graph illustrate the human relationship betwixt altitude and pressure using the default values for pressure and temperature at body of water level. Using ISA standards, the defaults for pressure and temperature at sea level are 101,325 Pa and 288 Thousand.

altitude to pressure conversion table

Conditions Conditions
Due to the fact that weather conditions bear upon pressure and altitude calculations, the force per unit area and temperature at sea level must be known. The altitude at a given air pressure can be calculated using Equation 1 for an distance up to xi km (36,090 anxiety). This equation tin be arranged to also calculate the air force per unit area at a given altitude as shown in Equation 2.

World'due south Atmosphere
Due to the fact that Earth'southward temper experiences dissimilar 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. Some layers, such as the stratosphere (from 11km to 20km), have a constant temperature throughout the layer. This requires dissimilar equations to decide the distance or pressure. Equations three and iv specify the calculation for altitude and pressure respectfully in this zero temperature lapse rate layer.

For these equations , , and correspond to the altitude, pressure, and temperature at the bottom of the stratosphere. The pressure level at the lesser of the layer is determined from the user provided inputs of the pressure and temperature at sea level knowing that the altitude at the bottom of the layer is 11 km; assuming the default pressure was used at bounding main level, the pressure at the bottom of the stratosphere is 22,632 Pa. The temperature at the bottom of the stratosphere is determined by subtracting 71.v Grand from the temperature at ocean level.
