A long 8-cm thick rectangular plate made of stainless steel at 304 (k= 12.9W/mk, ? = 7900 Kg/m3, C, = 477 J/kgK and a = 3.95 x 10-6 m²/s) comes out of an oven at a uniform temperature of 500°C. The plate is then allowed to cool slowly in a chamber at 150°C with an average convection heat transfer coefficient of h = 60 W/m²K. Determine the temperature at the center of the plate 120 min after the start of the cooling process.
