Infiltration of air into a flare system can lead to flame. burnback (also called flashback), which can initiate a. destructive detonation in the system. Burnback is one of. the primary modes of premature failure of a flare tip, and. can often be observed only at night. Air can enter the flare. system in one or more ways: through the stack exit by. buoyant exchange, wind action, or contraction of gases. due to cooling; through leaks in piping connections; or as.
Scale factor. The amount by which the image grows or shrinks is called the Scale Factor. Experiment with the scale factor slider to gets a feel for this idea. 1  If the scale factor is say 2, the image is enlarged so its dimensions are twice the original. 2  If it is 0.5, the image is reduced, with its dimensions half the original. 3  When the scale factor is 1, the image is the exact same size as the original.
In the context of populations, a limiting factor is a factor that causes population growth to decrease. Density-Dependent Factors Density-Dependent Factors A limiting factor that depends on population size is called a density-dependent limiting factor. Density-Dependent Factors Density-dependent limiting factors include: â¢ competition â¢ predation â¢ parasitism â¢ disease Density-Dependent Factors Density-dependent factors operate only when the population density reaches a certain level. These factors operate most strongly when a population is large and dense. They do not affect small, scattered populations as greatly. Density-Dependent Factors Competition When populations become crowded, organisms compete for food, water space, sunlight and other essentials. Competition among members of the same species is a density-dependent limiting factor. Density ...
