question

Consider a plane aluminum (k = 120 Btu/hr-ft-°F) wall at a steady temperature of 650°F. In order to increase the heat dissipation rate to surrounding air at 75°F, three aluminum pin-shaped fins per square inch are attached to the wall. Each fin is of 1/8 in diameter and 1 in long. Determine the percentage increase in the heat dissipation rate, if the coefficient of heat transfer is 28 Btu/hr-ft^2-°F.
