On a hot summer day, a cylindrical beverage can of 7 cm in diameter and 15 cm in length was taken out of the refrigerator and placed in an environment at 36 ° C. The outer surface temperature of the box is 4 ° C and the radiation emission ratio of the outer surface is 0.70. Since the ambient temperature is 36oC, find the total heat transfer amount from the side surfaces of the box to the environment under steady state conditions. If the box was left in a windy environment with a cross blowing speed of 3 m / s, what would the total amount of heat lost from the sides of the box be? Calculate.
