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.
Instructor: John Williams. Dilation is a key factor in regulating body processes. In this lesson, you will learn the definition of dilation, the purpose of it, and examples of its use in the body.ut when it is time for birth, the smooth muscle of the cervix relaxes, causing the cervix to dilate, or open wider. In this example, dilation is used by the smooth muscle of the cervix to allow the passage of a newborn child from the uterus to the birth canal.
