The floor in the auxiliary building is a concrete slab and measures The floor in the auxiliary building is a concrete slab and measures 75 ft by 85 ft. The floor thickness is 10 inches. The floor surface temperature is 70?F and the soil beneath the slab is 40?F. The thermal conductivity of the concrete is 0.85 Btu/hr-ft-?F. Calculate the heat transfer rate and heat flux through the floor slab.Engineering & Technology Mechanical Engineering NUC 245
