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.
Dilation. A dilation (similarity transformation) is a transformation that changes the size of a figure. It requires a center point and a scale factor, k. The value of k determines whether the dilation is an enlargement or a reduction.If | k. If | k. The absolute value of the scale factor determines the size of the new image as compared to the size of the original image.hen k is negative they are on opposite sides of the center. The center of a dilation is always its own image. Dilations preserve angle measure, betweenness of points and collinearity. It does not preserve distance.
