Consider a plane-parallel domain configuration That consists of a 5cm thick top later "A" and a 3cm thick bottom layer. There is a planar electrical heating element with negligible thickness, like an electric blanket, sandwiched between these two pieces, i.e. top and bottom plates. The heater generates power at a rate of 2,000W. The thermal conductivities of the Top and Bottom layers are 10.OW/m.K and 5W/m.K. Note that this is a one-dimensional, steady-state problem with negligible/no heat transfer from the exposed edges/sides of the system! The upper surface of the Top layer is exposed to air flow at T=10C with a convective heat transfer coefficient of h=10 W/m?K. The lower surface of the bottom part/layer is also exposed to air flow at 10C with a convective heat transfer coefficient of h=5.0W/m?K. a. Sketch the thermal resistance diagram with all the elements/nodes shown symbolically (no values yet). Then find the temperature of the heater when the system is operating at a steady state. (Hint: Kirchoff's Law is "a" possible approachO) b. For this case what are the temperatures of the exposed surfaces to air flow for the upper and lower plates? c. What are the rates of heat flow to the
