A 1.6-cm-thick wood floor covers a 4.0m×5.5m room. The subfloor on which the flooring sits is at a temperature of 16.2 celsius degrees, while the air in the room is at 19.1 celsius degrees. What is the rate of heat conduction through the floor? Use 0.200 W/m⋅K for the thermal conductivity of wood. Express your answer using two significant figures.

Q2) A constant heat flux (a -50 W/m2) is applied to a 1-D plane wall (k - 0.4 W/m K) on one side. The other side is subjected to convective boundary condition (h- 10 W/m? .K.Tm-25°C). A volumetric heat (q = 300 W/m*) is generated in the plane wall. If the plane wall has a thickness of L = 100 mm, a) Calculate surface temperatures T(x 0) and T(xL). b) Determine the location of the maximum temperature in the slab....

Problem Wall with Strip Heater The air inside a chamber is measured to be 50C and used to convectively heat a wall (h 20 w/m2 K). The wall (thermal conductivity of 4 W/m K) is 200 mm thick and has a uniform heat generation of 1000 W/m2. To prevent any heat generated within the wall from being lost to the outside of the chamber a very thin electrical strip heater is placed on the outer wall to provide a uniform...
