An inexpensive food and beverage container is fabricated
Chapter , Problem 1.12(choose chapter or problem)
An inexpensive food and beverage container is fabricated from 25-mm-thick polystyrene (k 0.023 W/m K) and has interior dimensions of 0.8 m 0.6 m 0.6 m. Under conditions for which an inner surface temperature of approximately 2 C is maintained by an ice-water mixture and an outer surface temperature of 20 C is maintained by the ambient, what is the heat flux through the container wall? Assuming negligible heat gain through the 0.8 m 0.6 m base of the cooler, what is the total heat load for the prescribed conditions?
