The external surface of a spherical container with the diameter D = 3 m has a temperature of 10° C. The container is surrounded by 30° C air, which is motionless except in the immediate vicinity of the container.
(a) Calculate the total heat transfer rate absorbed by the spherical container.
(b) It is proposed to replace the spherical container with one shaped as a horizontal cylinder with the diameter d = 1.5 m. This new container would have the same volume as the old one. Calculate the total heat transfer rate absorbed by the cylindrical container.
(c) Which container design would you choose if your objective is to prevent the warming of the liquid stored inside the container?
