Pyrex glass disks, 4 cm thick and 10 cm diameter at 1800ºC, are cooled in air at 30ºC for 5 minutes. The convective heat transfer coefficient is 10 W/m^2K and the Pyrex density is 2225 kg/m^3, thermal conductivity is 1.4 W/mK, and specific heat is 835 J/kgK. The maximum temperature difference through the pyrex must be less than 200ºC/cm. Determine what this is and make any recommendations.
