The building is required to have a floor area of 10,000 f2 and a height of 15 ft. It is proposed to use brick walls on three sides and a glass wall on the fourth side. Use the Lagrange multipliers to find the dimensions of the building to minimize the heat loss, assuming that the relative heat losses per unit surface area for the roof, brick wall, glass wall, and floor are in the proportion 3:2:7:1A cold-storage warehouse is to be constructed of a number of individual rooms that are maintained at various temperatures. The walls of one room are constructed of 4 inches thick masonry on the outside of 0.5 inches thick plywood on the side. Sandwiched between the masonry and plywood is glass fiber insulation that is 3.5 inches thick. The inside-wall temperature is to be maintained at −10°F and the outside-wall temperature is 70°F. As a first step in sizing the required cooling unit, determine the heat flow the wall on a per-square-foot basis.
