A round Bunsen burner ( 2cm diameter) supports a laminar flame. The flow approaching the flame has a standard Poiseuille velocity profile with an average velocity of 60cm/s. The flame is anchored to the edge of the tube, and the tip of the flame is 3.8cm downstream of the tube edge. From this information, estimate the laminar flame velocity, SL. You may assume that the flame near the tube wall is quenched when U(r)
