However, this force also increases drag substantially.The Bernoulli force shows up when the air over the top of the wing is faster than the bottom, but it requires a bit of cleverness to get it to work. The Kutta-Joukowski condition: If air didn't flow faster over the top of the wing, then the air from the bottom would have to whip around the trailing edge with a very high acceleration. K-J assures that this singularity at the trailing edge doesn't show up.Physicist: The narrative that usually leads to this question is something like: “It was the Wright brother’s brilliant wing shape, among other design innovations, that first made manned flight possible”.
It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events that have occurred during Earth's history.
For a given pressure the ideal gas law says that the density of a gas is inversely proportional to temperature, in Kelvin.
You can use this fact, the temperature and density of air (300°K 1.3 kg/m), and the temperature of your average run-of-the-mill open flame (about 1300°K) to find the density of fire.
For most “everyday” fires, the density of the gas in the flame will be about 1/4 the density of air.
So, since air (at sea level) weighs about 1.3 kg per cubic meter (1.3 grams per liter), fire weighs about 0.3 kg per cubic meter.
