In this tutorial will be addressed the optimization of heat transfer rate from
a cylindrical pin fin. A very long rod 25 mm in diameter has one end main-
tained at 100°C. The surface of the rod is exposed to ambient air at 25°C
with a convection heat transfer coefficient of 10 W/m .K. Determine the
2
heat loss from the rod constructed of pure copper.
