The cylinder barrel of a motor cycle (K=186W/m K), 0.15m high and 50mm in diameter. The outer surface of the cylinder is at a temperature of 500K and is exposed to the ambient air at 300K with convection coefficient of 50W/m²K. Annular fins of rectangular profile are added to increase the heat transfer. Assume that five such fins, 6mm thick, 20mm long and equally spaced are added. What is the increase in heat transfer rate due to addition of fins? Take fin efficiency as 0.95. The cylinder barrel of a motor cycle (K=186W/m K), 0.15m high and 50mm in diameter.
