Q1) One end of a copper rod (k = 380 W/m.K), 300 mm long is connected to a wall which is maintained at 300°C. The other end is firmly connected to other wall at 100°C. The air is blown across the rod so that the heat transfer coefficient of 20 W/m^2.K20W/m2.K is maintained. The diameter of the rod is 15 mm and temperature of air is 40°C. Determine : (i) Net heat transfer rate to air, (ii) The heat conducted to other end which is at 100°c.
