Answer:
The time required to reach the center line temperature of 800 K is t = 58 sec
Explanation:
Given data
D = 0.1 m
h = 100 
Specific heat for carbon steel (C) = 502.4 
Furnace temperature 
= 1200 K
Final temperature T = 800 K
Initial temperature 
= 300 K
From lumped heat analysis
------- (1)
Now from equation (1)
㏑ 0.44 = -(0.001415 ) t
-(0.001415 ) t = - 0.82
t = 58 sec
Thus the time required to reach the center line temperature of 800 K is
t = 58 sec
