A metallic solid cylinder has a diameter of 11 cm and initial temperature of 300oC. The cylinder is suddenly exposed to a convection environment with temperature of 50oC and convection heat transfer coefficient of 1200 W/m2 ◦C. When the cylinder loosed heat of 4.9 × 106 J/m what is the temperature of the cylinder surface? The physical and thermal properties of the cylinder material are: k = 204 W/m oC; Cp = 896 J/kg oC; ρ = 2707 kg/m3 ; and α = 8.4 × 10-5 m2 /s
