A 1600-W iron plate has a thickness of 5 mm, cross-sectional area of 300 cm^2. The room convection heat transfer coefficient is 25 W/(m^2K) with a temperature of 27 C. Determine the time required for the iron plate to drop from 1000 C to 50 C? Density, specific heat value and conductivity of the plate are 2650 kg/m^3, 900 J/(kgk) and 150 W/(mk), respectively.
