A spherical flask, 4 m diameter with a 5 mm thick wall, is used to heat grape juice. During the heating process the outside surface of the flask is 100ºC and the inside surface is 80ºC. Estimate the thermal resistance of the flask, the heat transfer through the flask, if it is assumed that only the bottom half is heated, and the temperature distribution through the flask wall.
