The cylindrical head of an engine is 1 m long and has an outside diameter of 50 mm. The temperature of outer surface is 150 °C and an ambient temperature 40 °C with a convective coefficient of 80 W/m?.'C. The head has been provided with 12 longitudinal straight fine, which are 0.75 mm thick and protrude 25 cm from the cylindrical surface. Calculate the heat dissipation due to addition of fines. Take thermal conductivity is 260 W/m.'C.
