You are designing a storage container for COVID vaccine. The volume of the storage container will be 1 m³. You are debating on three shapes: (a) a rectangular shaped box with 20-cm thickness, 1-m width, and 5-m length; (b) a cylindrical storage with 4-m length and 7.96 56.42 cm diameter, As part of your design decision, find out the convective heat transfer rate from each of these containers. Assume the surface temperature to be uniform at –10°C, and the ambient air is flowing at 20°C. The velocity of the air is 0.8 m/s. The direction of flow is over the 1-mx5-m sides of the box along the length (5-m) and across the cylinder and the sphere. Ignore the heat transfer from the end areas (i.e., the thickness of the rectangular box and the ends of the cylinder).
