Explanation:
Given:
Composite Wall
l= 4m b= 3m h= 3m
Area of rectangular wall lb = 4x3 = 12m2
L1 = 25 cm Fire brick
kı
= 0.4 W/mK
L2 =0.002m Steel
k2 = 54 W/mK
L3 = 0.08 m insulation
kı
= 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
