Carbon steel (aisi 1010) shafts of 0.1-m diameter are heat treated in a gas-fired furnace whose gases are at 1200 k and provide a convection coefficient of latex: 100\: \frac{w}{m^2.k}100 w m 2 . k. if the shafts enter the furnace at 300 k, how long (in seconds) must they remain in the furnace to achieve a center-line temperature of 800 k?
