Condensing fume is used to adhere-to a admission at 20 C. The fume careers through pipes that maintain the pipe deportment at 100 C. To extension ardor sell from the pipes, unspotted steel fins (k = 15W/ m-C), 20 cm covet and 0.5 cm in bisection, are welded to the pipe deportment as shown in Figure P13–11. A fan forces the admission air aggravate the pipe and fins,

resulting in a ardor sell coefficient of 50W/ m2- C at the deep deportment of the fin where it is welded to the pipe. However, the air career dispensation extensions the ardor sell coefficient to 80W/ m2- C at the fin tip. Assume the departure in ardor sell coefficient to then vary linearly from left end to just end of the fin deportment. State the temperature dispensation at L/4 locations acovet the fin. Also state the rate of ardor mislaying from each fin.
