A spherical tank, with an inner diameter of 3 m, is filled with a solution undergoing an exothermic reaction that generates 233 W/m3 of heat and causes the surface temperature to be 120°C. To prevent thermal burn hazards, the tank is enclosed with a concentric outer cover that provides an air gap of 5 cm in the enclosure. Determine whether the air gap is sufficient to keep the outer cover temperature below 45°C to prevent thermal burns on human skin. Evaluate the properties of air in the enclosure at 80°C and 1 atm pressure. Is this a good assumption?
