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.
Example 4 Integer scaling for density has been implemented, so that the integer 10000 represents a density of 1.0000 g/cm 3, and the integer 12000 represents a density of 1.2000 g/cm 3. The maximum integer is set to 12000.he scale factor is a ratio that converts the process variable range to the scaled integer range. The default scale factor is 1.1. Use the following equation to calculate the scale factor:where: - x1 = Lower range value (LRV) of process variable.
