Consider a wall with multiple layers. First layer is 20cm thick brick with 0.66 heat conductivity coefficient, second layer is 3cm thick grout with 0.6 heat conductivity coefficient, third layer is 8cm thick lime with 0.58 heat conductivity coefficient and the outer layer 1.2 cm thick grout with 0.6 heat conductivity coefficient. Walls inner and outer heat conductivity coefficient with order is 5.6 w/m2K and 11w/m2K. The room temperature is 22C and outside temperature is -5C. With these information please calculate the questions below. a) Total heat transfer coefficient b) Total heat resistance
