Question: plaster 3 brick a composite wall is 3m high and...

Question details

Plaster 3 Brick A composite wall is 3m high and 5 m wide wall and is made up of brick, plaster and foam, as shown. The foam side is exposed to 20°C air having h-10 W/mK while the other side is exposed to -10 °C having h-25 W/m-K. Given kbrick- 0.72 W/mK, Kplaster 0.22 W/mK and kfoam 0.026 W/mK 1.5 cm 22 cm A) Determine the rate of heat transfer through the wall assuming isothermal conditions at each x location 1.5 cm B) Repeat the analysis assuming surfaces C) Repeat part A) using a plaster D) Compare the results with the 2D parallel to the x axis are adiabatic conductivity of 0.1 W/mK numerical results presented in class (kplaster 0.22 W/mK261.6 W, kplaster 0.10 W/mK->q 230.4 W) 16 cm
