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.
The size of an enlargement is described by its scale factor. For example, a scale factor of 2 means that the new shape is twice the size of the original. A scale factor of 3 means that the new shape is three times the size of the original. 1  Page. 2  1. 3  2. 4  3. 5  4.
