Steel rods of 0.05m diameter are heat treated by being passed through a heat-treating furnace in which the atmosphere is at 700C. If the furnace is 5m in length and the rods enter at 50C, at what speed must they pass through the furnace to be at 600C when they leave the furnace? The heat transfer coefficient is 135 W*m^-2*L^-1.
