One wall of a house being remodeled consists of 0.019 m thick plywood, backed by 0.076 m thick insulation. The temperature at the inside surface is 25.0 0C, while the temperate at the outside surface is 4.0 0C, both being constant. The thermal conductivities of the insulation and plywood are, respectively, 0.03 and 0.08 J/(s. m.0C), and the area of the wall is 35 m2. Find the heat conducted through the wall in one hour and express the final answer in the British Units.

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?
