Consider the system below containing 3 conductive layers firmly connected together, with convection on both the outside and inside : The inside and outside convective heat transfer coefficients have values of h1=12.3Wm2K1 and h0 =49.9Wm2K1 respectively. Layers 1,2 and 3 have conductive heat transfer cocfficients of k1=0.286W m1K1,K2=0.087Wmm1K1 and k3=0.326Wmm1K1 and lengths of L1=0.226m,L2=0.05m and L3= 0.225m respectively. The wall has a total surface area of A=332.3m2 and the temperature on the inside and outside are Tj=111.2C and T0=25.1C respectively. Calculate the total rate of heat transfer across the wall in watts
