"Pin fins" of aluminum are to be compared in terms of their relative performance as a function of diameter. Three "pins" having diameters of 2,5 , and 10mm with a length of 5cm are exposed to a convection environment with T=20C, and h=40 W/m2.C. The base temperature is 200C. Calculate the heat transfer for each pin. How does it vary with pin diameter? How does q vary with the weight of the pin? (TB, Problem 2.133, 2.134)
