Cast-iron cannonballs used in the War of 1812 were occasionally heated for some extended time, so that when fired at houses and ships, they would set them on fire. If one of these cannonballs with a 20 cm diameter were at a uniform temperature of 1100 K, what heat flux value would exist if it were placed in still air at 300 K? You may assume no thermal radiation effects
