A straight rectangular fin has a length of 3.5 cm and a thickness of 1.4 mm. The thermal conductivity is 55 W/m middot degree C. The fin is exposed to a convection environment at 20 degree C and h = 500 W/m^2 middot degree C. Calculate the maximum possible heat loss for a base temperature of 150 degree C. What is the actual heat loss for this base temperature? 4641, 1140; If h = 68 W/m^2 middot degree C. Calculate the maximum possible heat. What is the actual heat loss? 631.2, 380.8
