Circular fins of uniform cross section, with diameter of 10 mm and length of 50 mm, are attached to a wall with surface temperature of 350°C. The fins are made of material with thermal conductivity of 240 W/m·K, and they are exposed to an ambient air condition of 25°C and the convection heat transfer coefficient is 250 W/m2 ·K. Determine the heat transfer rate, fin effectiveness, fin efficiency, and plot on the same plot the temperature variation of a single fin for the following boundary conditions: a. Infinitely long fin b. Adiabatic fin tip c. Fin with tip temperature of 250°C d. Convection from the fin tip
