Explanation:

Given:

Composite Wall

l= 4m b= 3m h= 3m

Area of rectangular wall lb = 4x3 = 12m2

L1 = 25 cm Fire brick

= 0.4 W/mK

L2 =0.002m Steel

k2 = 54 W/mK

L3 = 0.08 m insulation

= 0.2 W/mK

T1 = 6000 C

T2 = 600 C

Find

(i) Q (ii) (T3 –T4)

Solution

We know that,

ܳ

Here

(ΔT) overall = T1 – T4

And ΣR th = Rth1 + Rth2 + Rth3
