WebIf no heat is exchanged with the surrounding air during this process, which is called “adiabatic cooling”, the rate at which the air cools, the Adiabatic Lapse Rate (ALR) is a constant. For unsaturated air, the lapse rate is 3°C per 1000 feet; this is called the Dry Adiabatic Lapse Rate (DALR). WebAs a result, temperatures typically drop rapidly due to infrared heat loss. 05. There is a general tendency for the temperature to drop an average of 3.5 degrees F per 1000 feet as we ascend into the atmosphere, and to rise an average of 3.5 degrees F per 1000 feet as we move back toward the Earth's surface.

Air is all around us, but we cannot see it. Gravity from the Earth pulls air down - this is called air pressure. We don't feel this pressure because our bodies push an equal amount of pressure outward. This graph shows how air density and air pressure changes with altitude (the distance above sea level).

Webor roughly -1 degree Celsius per 100 meters of elevation gain, or -5.34 degrees Fahrenheit per 1000 feet. That’s the adiabatic rule for "dry air" that we all know and love. The rate for wet air calculates to be lower, because when wet air (100% humidity) rises and gets colder, some of the water turns from vapor to liquid and gives up latent ... WebIf, however, you want to go to extremes, you can take the cooling from 95°F to 65°F as an example. This is a massive 30°F drop in indoor temperature; it will take about 540 minutes (9 hours) of the air conditioner running at 100% output to achieve that.
