Q3/ Circular fin of rectangular profile is attached to a 3.0-cm-diameter tube maintained at 100°C. The outside diameter of the fin is 9.0 cm and the fin thickness is 1.0 mm. The environment has a convection coefficient of 50 W/m2. °C and a temperature of 30°C. Calculate the thermal conductivity of the material for a fin efficiency of 60 percent. 1 0.9 L = r2- L= 1. + 0.8 r = +Le 0.7
